Preparing graphics for DTG and DTF
Preparing graphics for DTG and DTF: While digital printing methods can handle photographic elements and gradients with ease, what most struggle with are semi-transparent pixels. Images are converted ready to print by a RIP (Raster Image Processor) and these look at, and convert the pixel information in a raster graphic or convert vector graphics, into raster images. A pixel with a 1% opacity is still a pixel with information and as such, some RIPs and print software will pick that information up as intentional.
