How to deal with PDFs and Vector art
A PDFs is essentially a files format that is a wrapper around other graphical content – raster and bitmap images, vector art or type. And vector art is a series of mathematical curves. But PDFs and vector art cannot by themselves be watermarked as they are not pure raster images. There are 2 ways to deal with PDFs and Vector art.
Of course the best practice is to encode raster images before they are used to make PDFs – but you already that knew, right?
- Extract the background image from the PDF or vector art and submit this raster image to Linkz for encoding. Then – re-insert the watermarked image into the PDF or vector art.
- Often rasterizing the whole PDF or vector will work. Gone are the days when professional RIPS had a hard time with large raster files – current RIPs chew ’em up and spit ’em out. Of course, your mileage may vary.
- Make sure your resolution is high enough for printing. Digital devices usually have 6oo DPI engines so rasterizing the art to 600dpi should work great.
- Watch out for type and other vector art quality. Rasterizing at a high enough resolution should not degrade the quality of vector art but your milage may vary.
