Abstract
In one example, a method for an inkjet printer that includes: converting original image data to rasterized data for printing with an inkjet printer; performing a first halftoning operation to modify the rasterized data for a visible independent effect, generating modified rasterized data; and performing a second halftoning operation on the modified rasterized data to generate halftone data for printing the image with the visible independent effect.
Claims15
A method for an inkjet printer, comprising:
- converting original image data to rasterized data for printing with an inkjet printer;
- performing a first halftoning operation to modify the rasterized data for a visible independent effect, generating modified rasterized data;
- and
- performing a second halftoning operation on the modified rasterized data to generate halftone data for printing the image with the visible independent effect.
A non-transitory processor readable medium having instructions thereon that when executed by a processor cause the processor to modify inkjet raster data for a flexographic effect.
A raster image processor for an inkjet printer, comprising:
- a conversion module to convert original image data to rasterized image data to print with the inkjet printer;
- an independent effects module to modify rasterized image data for a visible independent effect, the independent effects module including programming to:
- associate a set of halftone screens with image data in a print job, each halftone screen representing the visible independent effect for a different color;
- apply the halftone screen for each color to rasterized image data;
- and
- modify the rasterized image data according to the halftone screens.
An image processing method, comprising:
- rasterizing an image for printing with an inkjet printer, to form a rasterized image;
- and
- modifying the rasterized image to simulate printing the image with a flexographic printer.
