The Render section of the CTLW Karat output process template determines the output resolution and how Prinergy handles spot colors during CT/LW output to a Karat digital press.
JTP
Select the CTLW Output job ticket processor (JTP) to use for rendering.
Note: You set up JTPs in Prinergy Administrator.
Device Resolutions
This list is available when an output device format is selected in the Output To list.
Select a resolution for the selected device in the list.
Resolution X
Select 2400 dpi or 2540 dpi.
Resolution Y
Select 2400 dpi or 2540 dpi.
Color Model
Select the process color model to use for output.
The list of values varies, depending on the output format selected in the Output To list.
Shades
To set the number of shades of gray to output, select 1 for screened data or 256 for continuous tone data. When 1 is selected, the Calibration & Screening section of the refine process template is available for input.
The list of values varies, depending on the output format selected in the Output To list and the color model selected in the Color Model list.
Do Separations
Available when the output format selected in the Output To list supports separated output and DeviceCMYK is selected in the Color Model options.
Select if you want Prinergy to output separations. Clear this check box if you want Prinergy to output a single composite file.
Spot Color Handling
The options in this list determine how to handle spot colors on loose page output.
The list of values varies, depending on the output format selected in the Output To list.
- Select Convert to process to convert spot colors to process colors.
Note: When Convert to process is selected, Vector Overprint Handling (in the ColorConvert section) is automatically turned on to ensure the correct appearance of any overprinting spot colors. - Select Output separately to preserve spot colors on output.
- Select Don't output to suppress output of spot colors.
- Select Convert to process to convert spot colors to process colors.
Always Use Color Combiner to Convert Spots
This check box is available when Output Separations Handling is set to Convert separations to process.
If the input files contain overprinted spot colors, the Color Combiner, which is a plug-in to the renderer, will combine the layers and output the overprinted colors correctly.
When this check box is cleared, the renderer handles the conversion of spot colors to process colors if the following conditions exist:
- Input files are composite.
- All spot colors are set to opaque in the color database. (If a spot color is not in the color database, opaque is assumed.)
If the above conditions are not met, the Color Combiner will be used, even if the Always Use Color Combiner to Convert Spots check box is cleared.
Always select this check box.
See About Color Combiner.
Dielines Overprint Other Content
This check box is cleared and unavailable if the Do Separations check box is cleared and unavailable.
Select this check box to specify whether die lines overprint other content. Clear this check box if you do not want die lines to overprint other content.
The Dielines Overprint Other Content check box is available for the following outputs:
- DCS Raster
- Kodak Approval TIFF
- LQS TIFF
- VPS
- Windows Bitmap
Anti-Aliasing
Select this check box to enable anti-aliasing, and then in the at Ratio list, specify a ratio for anti-aliasing.
Anti-aliasing is a technique of improving the appearance of output by minimizing the "stair step" effect on rasterized output. It does so by rendering to a higher resolution than the intended output, and then downsampling to the intended output. This generates "averaged" pixels which softens the "stair step" effect on low-resolution output. The ratio value for anti-aliasing refers to the factor used to determine the intermediate resolution. A higher ratio results in higher quality, but can have an effect on output speed. For example, if the output is a 300 DPI 8-bit TIFF, and the anti-alias ratio is 4, Prinergy will render an intermediate output at 1200 DPI (4 x 300 DPI), and then downsample to the user-requested 300 DPI. Anti-aliasing is only available for 8-bit (256 shade) output.
Fail if font problems detected
Select this check box to fail the output process if a file has missing fonts.
Note: This feature is not available for vector outputs (PDF, PS2, PS3, EPS, DCS Vector, PDF/X-1a, PDF/X-3, CT/LW, and DELTA).
Ignore Embedded Fonts in Marks Files
Select this check box if you want Prinergy to ignore embedded fonts in a marks file and to look for the fonts in the system fonts folder.
Important: You must install the fonts in %ServerName%%AraxiHome%\AdobeExtreme\bin\fonts, or the output will fail.
Convert Text to Paths
This check box converts fonts to outlines before a file is RIPed.
This option was added in Prinergy 3.0 when the CPSI 3016 RIP was included with Prinergy. This option helped situations where the 3016 RIP failed to process the fonts on certain jobs.
This option has limited usefulness now, but is included as a potential workaround in rare cases where fonts are not rendered correctly by the RIP. It is not recommended that you enable this on on a permanent basis. When using this option for specific jobs, it is recommended that you ensure that both proofs and plates are output with this option.
Note that when you select the Convert Text to Paths check box, you will have text appear fatter on low-resolution proof output. You can overcome this appearance problem by either:
- Rendering to a higher resolution, if rendering to 1-bit output, such as Virtual Proofing System
- Using anti-aliasing, if rendering to contone output
Note: This check box is only available for raster output formats (.VPS, .TIFF, and so on).
Overlay Versioned Content
This check box applies to Layered PDF Versioning. For information, see the Versioning chapter in this guide.
Versioning Proof Mapping Color
This box applies to Layered PDF Versioning. For information, see the Versioning chapter in this guide.
Kodak Approval
Densities
Type an integer between -22 and +22.
For more information, see your Approval documentation.
CT/LW
CT Resolution
Type a resolution value in dots per inch (dpi) for the continuous tone (CW) files created during refine.
Note: 304.8 dpi = 12 dpm
LW Resolution
Type a resolution value in dots per inch (dpi) for the line work (LW) files created during refine.
Note: 2032.0 dpi = 80 dpm
Border Handling
Select the resolution at which the borders of overlapping images should be rendered:
- Borders to CT: Render borders at the resolution specified in the CT Resolution box. If two images overlap, the transition from one continuous tone (CT) image to the next may appear jagged.
- Borders to LW: Render borders at the resolution specified in the LW Resolution box. This improves the resolution of the overlap area but increases processing time and size of the output file.
- Borders to Smart Edge: Improves the appearance of CT-to-CT borders and ensures that the number of line work (LW) colors is not increased.
Output Kind
Select the format to which you want to output. You can output:
- CT/LW Job Only
- TIFF/IT Job Only
- CT/LW and TIFF/IT Jobs
- CTAndLW
- AllToCT
.
Force Vignette to CT
Select to convert gradations to the continuous tone (CT) layer and to convert gradations created as PostScript Level 2 to PostScript 3 (to obtain high-quality gradations when converted to CT data).
Converting to CT results in less banding and better quality images than converting to line work (LW). Converting to CT also adds noise to the resulting CT layers, creating a smoother image.
Note: If you clear this check box, some vignettes are still converted to CT data—for example, PostScript Level 2 gradations.
Force LW Vignette to CT
Select to convert the vignettes (gradations and blends) that AVR (Automatic Vignette Recognition) identifies to the continuous tone (CT) layer.
AVR recognizes a vignette as an image with a color difference (C, M, Y, or K) of 6% or less.
An output file in which blends are converted to CT is smaller than an output file in which blends are converted to line work (LW).
Screen Grabs
Select the resolution at which you want screen captures to be rendered:
- Grabs to CT: Renders screen captures at the resolution specified in the CT Resolution box.
- Grabs to LW: Renders screen captures at the resolution specified in the LW Resolution box.

TIFF/IT CT
When outputting to TIFF/IT, specify the file name ending for the continuous tone (CT) file. Type the file name suffix, which can include characters before the extension—for example, _CT.tif.
