Image for tarpaulin prints the whole thing in pure solid black
One customer brings his image to us for tarpaulin printing.
I copied the image from his USB drive and sent it into your Roland SC-545EX printer.
I have got no idea why the image prints in solid black, no image was printed, and it was just a solid black.
What I did just to print the image is to re-make the whole image in Adobe Photoshop then save.
Anyone can explain how it happened?
