Thanks. I'm just concerned that the crispness and quality wont be as good with a standard printer.
However, if that is not the case;
Which program/s do you use?
How do you define a transparent colour when making white writing that isn't a font?
And is the scaling generally accurate? Eg. If I measure 42mm on the loco, set the width to 42mm on the image, will it be 42mm? (I've noticed some programs and/or printer calibrations are inaccurate when practicing this.)
