I have had that. My thinking on it - file began as SVG, in Affinity Designer I placed a graphic into the design (it was actually a shape of a dragon fly). Copied and made several shapes. Resized all to what I wanted. Exported as an EPS or PDF (not sure what I used) When I opened RasterLink6 to print them on my Mimaki CJV150-75, all shapes increased in size. Not sure why. I am still trying to learn Affinity and it causes much frustration, as now I don't trust or understand the program, so I went back to Corel Draw to get the order done.
So, my story leads me to ask - Are you using new software? What type of file was used in making the design that was printed? How many other programs were open on the
computer when Rater Link was used to send the design over to the printer? Asking because computers with the minimum requirements to run the programs, have issues....don't ask me why I know this.
