EcoPRO FAQ Answers1.1 How many lines per inch (LPI) can I print with EcoPRO? Or, stated another way, what is the maximum screen frequency I can print? There is no magic number to answer this question, because it boils down to a trade-off between gray scale range--which translates to color range on the final screen-printed product--and spatial detail. In other words, with an imaging device at a given resolution, such as EcoPRO, two things happen when your screen frequency is increased:
(Back to FAQ'S)
1.2 For which screen printing applications is EcoPRO best suited? At a base resolution of 400 dpi, EcoPRO achieves a quality level surprising to many who are accustomed to seeing higher resolution output. Some of the reasons for this are:
Even with this high level of quality, EcoPRO is not designed for every printing application. Many printing applications require higher resolution output devices. The best applications for EcoPRO are those using line screen frequencies of 65 lpi and below, and that place a higher priority on registration than on dimensional accuracy (see Question 4 in this section for more on registration and accuracy). The screen printing product specialties that EcoPRO addresses best are shown below, along with the percentage of screen printers in the US that produce at least some of this specialty. The percentages were provided by the Screen printing and Graphical Imaging Association International (SGIA).
Textile garments are the most widely produced screen printing products, and are also the best fit for EcoPRO. The reason is that the soft, textured substrates used do not require resolution higher than EcoPRO's capabilities. High resolution devices are often overkill for this application because:
A wide variety of signs, small banners, and POP displays can also be produced using EcoPRO. Some of these applications are accustomed to using higher resolution films, e.g. 1,000 dpi and higher. Some may actually require higher resolution, and the screen frequency they use is a good indicator: If it is significantly higher than 65 lpi, they may not be satisfied with EcoPRO films. Beyond those that truly require higher resolution than EcoPRO can provide, there are others who are used to working with higher resolution, even if the application does not really need it. The best way to test this is to burn a screen using EcoFilm separations. This will often overcome skepticism; many have been pleasantly surprised with the output quality. IMPORTANT: Comparing films is not sufficient. The important comparison is the quality of the final screen printed product, using the screens burned from the films. (Back to FAQ's)
1.3 What types of color processes can use EcoPRO? Spot color? Process color? First, what is the difference between process color and spot color?
Process color (CMYK) combines the primary colors--C stands for cyan, M for magenta, Y for yellow, and K for black--in combinations of halftone patterns to produce secondary colors. As shown above, cyan and yellow combine to produce green, magenta and yellow combine to produce red, and cyan, magenta and yellow all combine to produce black. In CMYK printing, there is an additional premixed black ink. These 4 colors can be mixed in varying halftone percentages to produce millions of different color patterns. For example, use a higher percentage of yellow with magenta, and instead of red you get orange. When printing CMYK process color, 4 separate films are used, one for each primary color. These films are commonly called film separations, or simply separations. Process color produces a wide range of colors in an efficient, cost effective manner Spot color uses premixed inks for each printed color. One film separation is used for each color. Though simple print jobs may require only 1 or 2 spot colors, the use of 6-8 colors is common, and some jobs use more than 20 colors. There is a wide range of total colors available. For example, Pantone Corporation has defined and numbered over 1,000 spot colors. The spot color process is less efficient than process color, but is more forgiving in the printing process. In process color, all of the color mixing is dependent on precise dot formation and alignment. Dot formation must be consistent, registration error must be minimized, screen angles for each film separation must be precise, etc. Using spot color, because each color is premixed, the process can be less precise and results will still be good. EcoPRO, because of its precision and consistency, can print both process and spot color. With process color, it is particularly important to stay within the guideline of 65 lpi and below. Also, it is important to keep the thermal head and the rollers clean; this helps keep registration error at a minimum. (Back to FAQ's)
1.4 What is the difference between accuracy and registration, and what are the accuracy and registration expectations of EcoPRO? Accuracy refers to dimensions on a single page or film separation. Accuracy error is the difference between a specified dimension of an object in a design and the dimension of that same object when printed. For example, if you define a line to be 8 inches long and it prints out at 8.039 inches, the accuracy error is 0.039 inch. Registration refers to how well design elements of two or more film separations align with one another. Registration error is the degree of misalignment. For example, if you align the top registration targets of two film separations, and the bottom targets are misaligned by 0.005 inch, the registration error would be 0.005 inch, or five thousandths. What about the accuracy and registration of EcoPRO? Accuracy error varies among individual EcoPRO units because of very slight differences in dimensions of certain parts. An example is the diameter of the grit drive roller, which transports the film across the thermal imaging head. Worst case accuracy error will be less than ± 0.100 for a 12x 18 inch image. This error will occur along the media travel axis, and will be very close to linear. In other words, the error over 9 inches of media travel will be approximately half of what it is over 18 inches. There is no accuracy adjustment on EcoPRO. The good news is that the accuracy of a given EcoPRO Imager is highly repeatable. If that 8 inch line comes out to 8.039 inches when printed on a film separation, then it will be virtually identical on all separations. One of EcoPRO's strengths is its registration. Because it is highly repeatable from separation to separation, registration for two or more 12 x 18 inch film separations is consistently less than 0.005 inch. In most screen printing applications registration is more important than accuracy, because good alignment of separations produces sharp detail and consistent color rendering. Some label and decal applications place extra emphasis on accuracy; in these cases the user will want to characterize their unit and compensate accordingly. One other note on EcoPRO accuracy: Dimensions along the media travel axis will be slightly longer for film than for paper. The reason is the grit drive roller penetrates paper more than film, effectively reducing the diameter of the roller. Also, film is a more stable media dimensionally than paper. For these reasons, film should be used when characterizing the accuracy of a unit; film also produces the best registration results. (Back to FAQ's)

1.8 What is stochastic screening? Does EcoPRO support it? Stochastic screening uses mathematical algorithms to randomly space pixels within an established framework. In other words, it is not completely random, but to the human eye does not have a discernible order. The result is variable spacing of dots, which differs from a conventional tint or halftone. Variable dot spacing is also referred to as frequency modulated, or FM, screening. The examples below show the differences between stochastic and conventional rendering techniques.
EcoPRO supports first order stochastic screening in the raster mode of the windows 95 / 98 / NT 4.0 driver. However, stochastic screening is a promising but unproved rendering method for screen printing. Most screen printers have achieved better results so far using conventional halftone rendering. (Back to FAQ's)
1.9 Does EcoPRO print gray scale? Like most imaging devices used in commercial printing, EcoPRO prints different levels of gray by printing halftones. EcoPRO prints are made from two binary choices:
Combinations of these black dots and unimaged space are grouped together in ordered patterns called halftone dots to produce shades of gray--and hence shades of color on the final print. Devices that can print shades of gray at the fundamental pixel level are called continuous tone gray scale devices. Examples of this are dye sublimation printers and conventional cameras. Refer to FAQ 1 in Pre-Sales Questions for more on the halftone gray scale capability of EcoPRO. (Back to FAQ's)
1.10 I have been told there are 2 models of EcoPRO. What is the difference? What is included in the Network Upgrade Kit? When EcoPRO was introduced, two models were available: the Standard model (53412EG) and the Network model (52412EG MX). Due to the overwhelming preference for the Network model, the Standard model was discontinued in April 1997. The network model has all of the features of the Standard model, plus the following:
The Network Upgrade Kit includes everything required to convert a Standard unit to a Network unit. (Back to FAQ's)
1.11 What is the memory capacity of EcoPRO? Can I buy off-the-shelf memory? What are the memory specifications? Refer to the table titled Maximum Page Length vs. Installed Memory in the Product section. (Back to FAQ's)
1.12 How is EcoPRO serviced? What is the warranty? What is the price of a maintenance contract beyond the warranty period? Who do you call when you have problems? The EcoPRO printer is serviced by the factory. During the Warranty period of 1 year, if the unit fails it will be replaced by EcoPRO Imaging. An annual service contract is available. With this contract if a unit fails it will be exchanged by EcoPRO. A replacement unit will be shipped to the customer, and arrangements made to return the failed unit. (Back to FAQ's)
Installation and Setup 2.1 What cabling is needed to interface EcoPRO to a PC? A Mac? Two types of connections can be made to the EcoPRO printer: Centronics and Ethernet. There are two connectors for Ethernet: RJ45 and AUI. RJ45 is the most common, but the AUI connector can be adapted to other Ethernet cable types, such as ThickNet (10Base 5) and ThinNet (10Base2). For PC's in a stand-alone environment the common connection will be the Centronics connection. This connection uses a standard parallel printer cable that connects from the PC's LPT port to the printer Centronics connector. For Macintosh computers the RJ45 connection (10BaseT cable) on the Ethernet card is most commonly used. The cable required is an RJ45 twisted pair Ethernet patch cable. The included L-COM adapter (Part Number EC535D-10X) is used to convert a standard Ethernet cable to a cross-pinned Ethernet cable configuration. This device may be needed to connect the EcoPRO printer directly to a stand-alone computer. To test if this adapter is needed, follow these steps:
Most Macintosh Power PC computers have both the RJ45 and AAUI Ethernet ports. Early Macintosh Power PC's had only an AAUI Ethernet connector. If you have one of these, you will need to purchase a transceiver to convert from AAUI to 10baseT (RJ45) (Back to FAQ's)
2.2 What are the current firmware and software versions The current firmware versions for the EcoPRO are:
The Software drivers for PC/Windows computers are:
The current versions of the PC/Windows software are available on the EcoPRO Imaging web site, and ftp site. The web site address is: www.ecoproimaging.com The current software for the Macintosh is:
The LaserWriter driver is provided by Apple along with the Macintosh operating system. Apple also has LaserWriter driver updates available on its web site. Select in order: Tech Support On-line, Printers & Imaging, appropriate driver version. EcoPRO works with LaserWriter 8.3.4, 8.5.1 and 8.6.5 IMPORTANT: Version 8.4.2 does NOT support custom page sizes. If you want to print custom page sizes, we recommend using 8.5.1 or newer. If you have a LaserWriter driver and are not sure of the version, do the following:
EcoPRO Imaging ships the PPD (PostScript Printer Description) with each EcoPRO Imager. The PPD works in conjunction with the LaserWriter driver, and defines EcoPRO's unique characteristics, such as resolution, image size, and media types. To verify the file version of your PPD:

2.3 How do I upgrade my EcoPRO to the latest firmware? Firmware 1.10p Upgrade Instructions STATUS VERIFICATION
If the BOOT version is 1.01 or 1.01P, then skip steps A-C and G-I (setting BOOT protect jumper) of the upgrade instructions. INSTALLATION INSTRUCTIONS
Install the write enable jumper (right-most jumper pair of J8) located inboard of the SIMM sockets. See Figure 1. WPR jumper removed = Boot write protected (Default)
Figure 1
If printed circuit board has no title printed near DRAM SIMM socket, do the following: Remove write protect jumper (right-most jumper pair of J8) located inboard of the SIMM sockets. See Figure 2. WPR jumper installed = Boot write protected (Default)
Figure 2
NOTE: For printers networked and serviced by network queues, the firmware upgrade can be sent thought the existing queues. The redirection of an LPT port to the network queue must be done prior to running the upgrade file. This must be done by the system administrator.
(This is important because upgrading the firmware by downloading with the LaserWriter Utility may hang your Macintosh, possibly resulting in unsaved data being lost.)
g. Remove the DRAM and FLASH SIMM's. See 6-13 of the Operators Manual. h. Return the Write Protect Jumper on the J8 jumper block to the default configuration (see step b). i. Reinstall the DRAM and FLASH SIMM's CHECKOUT PROCEDURES
2.4 How do I set up the EcoPRO on a network? There are several network configurations on which the EcoPRO will work:
When connecting the EcoPRO to an existing EtherTalk network, plug a standard RJ45 10baseT cable from the network Hub to the EcoPRO RJ45 connector on the Ethernet card. The Macintosh computers should have AppleTalk configured to work over Ethernet. For older Macintosh systems launch the Network control panel and then select EtherTalk. For newer Macintosh computers launch the AppleTalk control panel and then select Ethernet. Open the chooser and select the LaserWriter driver. The EcoPRO should show in the printer window. If the EcoPRO Imager has firmware version less than 1.03, the GX option on the printer control panel needs to be set to OFF. This option is found under MORE OPTIONS in the PRINTER CONFIG menu. If this option is set to ON the printer will not broadcast itself as a LaserWriter device for Macintosh systems. The following LaserWriter Driver problems have been identified. If the LaserWriter Driver version prior to v8.3.4 is being used, you may have Network communication errors: A couple of pages are printed and errors occur. If the LaserWriter Driver version 8.4.x is being used, custom paper size cannot be selected in the Page Setup dialog. If either of the above problems are occurring, please install the LaserWriter Utility v8.3.4. This version is available only from Apple. Please contact them for the software or for further a assistance. Their Web site address is: http://www.apple.com Configuring a EcoPRO with the Ethernet card on Novell.

2.5 I installed a 32 MB SIMM, but my Macintosh shows only 4 MB available Go to the Chooser on the Apple menu, select the appropriate LaserWriter driver, and choose EcoPRO. Then select:
This will cause the driver to go out and query the EcoPRO for the latest configuration. After this procedure, the correct amount of memory should appear. (Back to FAQ's)
2.6 Can I connect EcoPRO to an EtherTalk network? A LocalTalk network? The EcoPRO supports EtherTalk through its internal Ethernet interface, through either the RJ45 or the AUI connector. The EcoPRO does not support communication over a LocalTalk network. The reason this was not provided is that Ethernet's maximum transmission rate is about 100 times faster than that of LocalTalk. Today's large, complex PostScript files take far too long to process over a LocalTalk network. All PowerMacs come equipped with the Ethernet connections required to connect to an EcoPRO Imager. Older Macs may not have these connections. There are several third party Ethernet interfaces available for the older Macs. Ask your local Macintosh dealer. (Back to FAQ's)

2.8 The unit won't initialize at all. The LED is blank. The panel has these "BLANK" conditions:
If the display has no output and no back-light the display may be faulty, The cable may be disconnected or there maybe some other interruption of power to the display. Check that other parts of the printer have power: The Ethernet card LEDs, fan. etc. Also check that the cable to the control panel is not damaged or disconnected. If the display has solid black squares, the boot code has been corrupted and requires a reload. This operation needs to be done by the factory or a qualified service technician. (Back to FAQ's)
2.9 Get"Initializing 6" message, then the unit hangs For units with a Ethernet board, it is possible that on power-up, the EcoPRO printer will hang displaying the message:

2.10 When I close the lid, the control panel still reads "Cover Open" The cover switch is located on the left inside wall of the EcoPRO printer. It is activated by an actuator attached to the lid. The switch can be tested by manually pressing the switch while monitoring the control panel display. The display should change back to ONLINE a few seconds after the switch is depressed. If the switch is OK, then check that the actuator contacts the roller arm of the cover switch. If the actuator is pressing on the roller arm of the switch but the display does not change, the switch may be out of adjustment. The switch is mounted on a mounting plate that has elongated holes to allow the switch to be adjusted. Loosen the mounting screws and position the switch so it activates when the cover is closed. If activating the switch manually does not cause the display to change, the switch or the electronics on the motherboard may be faulty. Either case requires a part replacement by the factory or a qualified service technician. (Back to FAQ's)

3.2 I am having trouble getting the proper print results. I am experiencing one of the following:
This establishes the proper size, margins, and other options for the design, and should be properly established at the onset of the design process. Document Setup/Layout is controlled by the application (e.g. CorelDraw, Illustrator, etc.), but is closely related to Page Setup. Some tips on choosing document layout size:
b. Page Setup Page Setup is used to set up the page for printing. It is controlled by the printer driver and the PPD specific to the output device, in this case, the EcoPRO PPD. It is usually best to match document size to page size in document setup. Some other tips:
c. Separation Setup Separation Setup is for the special settings that relate to film separations. It is application specific, but the functions are basically the same for each application. This area has tripped up many users who thought setting up the document and the page was enough. Some tips to avoid such problems:
d. Print This selection is where you execute the command to PRINT to EcoPRO. Before printing, check these areas:
(Back to FAQ's)
3.3 I get an "insufficient RAM error"; or I can't print as large a page as I want; or what is the page size capability? An insufficient RAM error indicates that there is not enough random access memory (RAM) in the EcoPRO Imager to process the current job. Memory for an individual job are affected mainly by two variables: page size and the print resolution. If either of these is increased, more memory is required. (Back to FAQ's)
3.4 The page orientation is wrong Page orientation is set by selecting portrait or landscape from the application or driver. This selection will rotate the image within the defined paper size. This selection will not rotate the defined paper size. If the paper size is defined as width 8.5" height 11" then the output will not fill across the 12" roll. It will use 8.5" of the roll media. Selecting landscape will only rotate the image within the same paper size so the output will still only fill 8.5" of the 12" roll. To make the image use 11" of the 12" roll, select custom page size with the width 11" and the height 8.5". Some of the page sizes are defined as transverse; for example, letter size is defined as "letter" and "letter transverse". For sizes not defined, then use the custom size to define page sizes to optimize the width of the 12" imageable area. (Back to FAQ's)
3.5 I am not getting the resolution I expected on my output; or what is the resolution capability? The basic resolution of EcoPRO is 400 dots per inch (dpi). This resolution is enhanced by the capability of addressing more dpi in the direction of film travel. This does not reduce the size of the dot, which remains 1/400th of an inch. It simply increase the number of dots that can be printed on one axis (the dots print across the film at 400 per inch independent of resolution setting). EcoPRO offers printing at 400 x 400 dpi, 400 x 800 dpi, and 400 x 1,600 dpi. Why print more dots when dot size is not reduced? There are two main benefits:

3.9 How long does it take to print a file? The time to print a file is virtually impossible to determine. The size and complexity of the file, along with the number of fonts, both printer resident and downloadable soft fonts, the output page size, computer speed, output format (CCRF or PostScript), Foreground or background printing, and network traffic can all play a factor in the time for the printer to print. If the printer is receiving Raster (CCRF) data, it will begin to print as soon as the data has filled the printer memory. In CCRF mode the memory is used to buffer the print job so the printer will not starve for data and have to stop and start during the print job. If the print job is larger than the available printer memory, the printer will print while continuing to receive data. If the printer is receiving PostScript data it will have to receive the entire print job prior to starting to process the PostScript job. After the print job is received the printer processing time will depend on the print job size, fonts, output size and output mode. Generally the larger the job, the more fonts used, the larger the output size and the higher the resolution, the longer the job will take to print. (Back to FAQ's)
3.10 The unit is printing twice the length it should (or half the length) The printer has print modes that input 400 x 400, 400 x 800 and 400 x 1600 DPI. If the driver is set to "use printer value" then the data may not match the setting of the printer. For the Macintosh make sure to set and :SAVE" the print settings in PRINT MODE, found in the PRINT dialogue box under the FILE menu. While you are at it, set and save the other options as well (cut..etc.). For Windows NT make sure the values are set as the default settings. This is done by highlighting the printer in the printers window and selecting file, document defaults, then setting the desired values. (Back to FAQ's)

3.13 I can't get high resolution output from CorelDraw If you are running CorelDraw in Windows 95 / 98, the first step is to make sure you are using the latest driver for Windows 95 / 98. CorelDraw saves the default settings on the default printer when it starts. Any changes made to the printer driver by using the "Printers window" will not change the settings for CorelDraw. To modify settings to the printer with CorelDraw, they must be done from Corel's print setup, or from the print function and selecting print options. (Back to FAQ's)

3.16 I get a communication error after printing the first separation This problem may be a LaserWriter Driver problem when using Illustrator. Make sure you have LaserWriter 8.3.4 or newer. Intermittent communication problems can also be a result of faulty cabling, Ethernet hubs or a faulty Ethernet card in the printer. Some large files with separations from illustrator have intermittent hangs. They can cause the Ethernet card to become corrupted. If this happens then reset the Ethernet card.

(Back to FAQ's)
3.18 I get blank space between separations The printer will put a small blank area between pages. Normally 1/2 inch. If the area seems larger than this then verify the printer page size is the same size as the image, or application page size. One way to check the output page size is to include crop marks or registration marks. These are on the edge of the page. Also if the application has a print preview function, this will show how the image will fit on the selected page size and show the amount of blank area that will be printed. (Back to FAQ's)
3.19 Scaling is off when using custom page sizes Scaling is typically controlled by the application. Functions such as fit to page, maintain aspect ratio, page numbers and titles can modify the final output size. The printer has no scaling capability, this function is a setup of the driver or application. Make sure the application settings are correct and that scaling settings in the driver (If available) are set as desired. Some applications will override scaling settings of the driver while others will allow the driver scale setting to be applied. Verify that scaling is done by either the driver or the application, but not both. The best method is to do the scaling in the application when it's available. (Back to FAQ's)

4.2 I cleaned my thermal head carefully, but I am still getting streaks, voids or other image artifacts on my film separations. The Routine Maintenance section of the EcoPRO Operator's Manual has detailed cleaning instructions. Follow them carefully. Here are a few extra cleaning tips:
(Back to FAQ's)
4.3 The thermal image head is defective It is possible that the thermal head is defective. It could be scratched, or simply worn out from use over time. However, what appears to be a defective head is often just a dirty head. If a small amount of debris gets baked on to the head, the result is a streak or scratch that runs in the film travel direction. Follow the thermal head cleaning instructions carefully, including the extra tips provided in FAQ 2 under Printing PostScript Files. (Back to FAQ's)
4.4 There are lines down the image in the direction of film travel Refer to the previous question and cleaning tips in FAQ 2 under Printing PostScript Files. (Back to FAQ's)
4.5 Lines or stripes are showing up that run across the width of the film (in the direction of the thermal imaging head). This may be caused by a dirty thermal imaging head. Debris baked on the head may cause film to stick to the head, causing an uneven film travel that can lead to lines/stripes across the width of the film. Follow the thermal head cleaning instructions carefully, including the extra tips provided in FAQ 2 under Printing PostScript Files. Also, clean the media hub saddles with alcohol. Sticky saddles can make the media jump and chatter, which can cause lines/stripes. Also inspect the area of the hubs that rub on the saddles. (Back to FAQ's)
4.6 Lines are appearing on the right side of scanned images. This is caused by anomalies in earlier revisions of firmware and driver code. Be sure that the unit has the current firmware installed and that the most current drivers are being used. Please refer to FAQ 2.2 for version information.
