General Information 3 B. GENERAL INFORMATION - Printheads: Color order and positioning This schematic overview shows us that we immediately can print white followed by a color in one print run. This is called “Pre-white” printing. tthe 2 white printing heads are aalternately jetting to achieve tthe optimum printing speed... If we want to print color first, and white on top, we need to do it in two separate print runs, using the “C/W” and “feedback” option in the AgfaRip.
White applications C. White applications: Pre-White: Print on frontside of a media, normal printing. To be used on all Frontlit applications, on Transparant as well as on Opaque substrates. Post-White: Print on the backside of a media, mirror/wrong reading printing. To be used on all Backlit applications on Transparant substrates.
The Day&Night application 5 The Day&Night application: 1st printrun 2nd printrun + Only color + text mirror image = pre-white e-white + color no text, mirror image The purpose of this application, is to reach the same visual effect with and without light emitted through the back of the image. Most backlight applications look as they should, when light is emitted through the back, but look too dark when the light is turned off. We use a clear plexi, or a glass surface for this application.
The Opaque white application & Post white The Opaque white application: This application is printed on the back side of substrate, mirror/wrong reading printing. Used on Transparent media, such as clear plexi or glass. color pre-white + color mask It’s a combination of a color print (1st printrun)... pre-white + color file followed by a “PreWhite” colored mask (2nd printrun)...
Preparing an image 7 D. Preparing an image: We will show you how-to, by going step-by-step through the next photoshop example….

Preparing an image We now have to delete the parts which will be printed only with white ink, so the areas with no other color on top… Make the spot channel invisible again, by toggling the channel visibility… Delete the white in areas… The T white ink areas are now deleted from the t CMYK layer, but are still present in the Spot channel layer. You can check this by S toggling the CMYK color channel visibility… t Save your image as a .Tiff or a .
