1. A system for printing on clear polymeric film web, comprising:
a first stationary inkjet print unit having first ejection nozzles that span a width of the clear polymeric film web;
a second stationary inkjet print unit having second ejection nozzles that span the width of the clear polymeric film web;
a web transport that conveys the clear polymeric film web past the first and second stationary inkjet print units;
a distortion corrector that adjusts dimensions of a page element to be printed in accordance with predetermined distortion data to develop an adjusted page element, wherein the dimensions are adjusted to compensate for expected shrinking of the clear polymeric film web after printing, the distortion corrector being further adapted to determine dot gain changes as a result of the shrinking and to adjust image data of the adjusted page element to compensate for such dot gain changes;
a raster image processor that rasterizes printing commands associated with the adjusted page element to generate bitmap data;
a first print controller adapted to receive the bitmap data and in response operate the first stationary inkjet print unit to deposit drops of a first material on the clear polymeric film web in accordance with the bitmap data at a first resolution; and
a second print controller that receives the bitmap data and in responses operates the second stationary inkjet print unit to deposit drops of a second material on the clear polymeric film web in accordance with the bitmap data at a second resolution,
wherein the first and second resolutions are different.
