Abstract
Gloss, differential gloss, and image relief of a printed image may be controlled by utilizing a combination of technologies in the appropriate manner. These technologies include the use of transparent toner overcoats, negative transparent toner masks, variable screen transparent toner screen masks, UV coaters, and post-press belt fusing. Unlike conventional systems, which may increase gloss at a cost of also increasing image relief, the present invention may produce an image having a controlled gloss, differential gloss, and image relief.
Claims9
A method for controlling gloss and/or differential gloss of a printed image comprising:
- applying a color toner lay-down onto a media substrate to form a pre-fused image;
- determining image height of the prefused image;
- determining a negative mask of transparent toner based on the prefused image height, desired gloss and/or differential gloss;
- applying the transparent toner over the prefused image;
- fusing said pre-fused image to form a fused print.
A computer readable media for controlling gloss, differential gloss and image height of a printed image on a substrate comprising:
- a code segment for obtaining a desired level of gloss and differential gloss from a user;
- a code segment for reading an original image from which said printed image is to be made and calculating an image height of a color toner lay-down of said original image;
- a code segment for calculating an appropriate negative mask application of transparent toner based on the image height of said color toner lay-down of said original image, said desired level of gloss and said differential gloss and said substrate;
- and a code segment for applying the transparent toner over the color toner lay-down;
- and a code segment for fusing an image formed by the color toner lay-down and the transparent toner to form a fused print.
