Screen printing queues
Color conversion of images depends on the selection of a reference profile that serves as a “separation” profile. This reference profile is embedded in the printer profile used by the queue.
For example, to set up generation of halftone separations from an RGB image, you could:
- Select Adobe RGB as the input profile (set on the Input tab).
- Select ISO Coated ICC as the separation profile (embedded in the printer profile set on the Output tab).
PrintFactory in turn:
- Converts the supplied image from RGB to CMYK with reference to the profile settings.
- Generates halftone separations from the resulting CMYK image.
ICC profiles and rendering intent
You can set the input ICC profiles and rendering intents for images and vector graphics.
If you’re going to print images or vector graphics of a given color space to this queue, it is strongly recommended that you select and ICC profile for that color space. If the workflow uses a known ICC profile, you can use that profile. If you select the RGB to Gray profile, conversions are from RGB to Lab Gray.
For the Cie Lab color space, PrintFactory always uses the CIE Lab D50 profile.
For proofing queues, it is recommended not to select any profiles.
Honor embedded profiles
Images and vector graphics may already be tagged with an ICC profile. If you expect this to be the case, you can select the option Honor embedded profiles. The ICC profiles embedded in images and vector graphics will then take precedence over the input ICC profiles you specify for the PrintFactory Queue.
For proofing queues, it is recommended not to select this option.
Pure hue
Select Pure hue if you want to print text and vector graphics using pure primary and secondary colors (red, green, blue, cyan, magenta, yellow).
This option turns off color management for text and vector graphics composed of primary and secondary colors, but not for images. In other words, only vector elements that are built up with primary and secondary colors are printed with pure ink colors. For example, a yellow vector element is printed using yellow inks only. The resulting output is pure yellow, but colorimetrically incorrect.
For proofing queues, it is recommended not to select this option.
