Abstract
There is disclosed a computerized prepress system having imposition means for receiving from a digital storage means at least one digital representation of at least one page and for arranging this digital representation in accordance with a desired plate layout, to define a digital plate image and, ghosting prediction means coupled to the imposition means. These ghosting prediction means are operable to make a ghosting prediction based on data from at least one of the digital plate image and a relatively low resolution version of the data.
Claims19
A computerized prepress and press system, said system comprising:
- imposition means for receiving from a digital storage means at least one digital representation of at least one page and for arranging said at least one digital representation in accordance with a desired plate layout, thereby to define a digital plate image;
- and
- ghosting prediction means coupled to said imposition means, operable to make a ghosting prediction based on data from at least one said digital plate image and a relatively low resolution version of said data, where ghosting will occur.
A method for creating a digital image of a printing plate, comprising the steps of:
- creating a first digital image of said printing plate, using digital representation of at least one page and given coordinates thereof on said printing plate;
- using said first digital image of said printing plate to predict where ghosting will occur on said printed image;
- using said first digital image of said printing plate and said prediction to create a second digital image of said printing plate, comprising ghosting prevention bar.
