Corel help, please! Differing sizes on same file output.
HI all,
I’ve had this happen on a few occasions now, I make a file in corel X5, send the print part to my trade printer (solvent) or my own HP aqueous printer and print the job no problems, In this example I’ve cut some reflective lettering which is going to overlay the printed text on the print, when I overlay it on the print it is short, fine in height but in length it loses about 8mm on a 650mm long run of text.In another instance I printed onto reflective, then wanted to lay that onto some clear vinyl to make it easier to remove, same problem, the printed reflective was too big to fit on the clear vinyl and a lot of messing about was needd to make underlays of the right length.
I print direct from corel to my HP, corel winplot to the plotter, and my trade printer uses corel to open my original files and sends them to print via his rip.
if I cut layers of vinyl with reg marks there is often a couple of mm error margin over 12-1500mm but the print / cad is just waay off!
Any ideas why this happens?

Providing there is no slippage of the material then all down to calibration of the different thickness of materials.
Quick get out of jail is if just one line of text is to print cut all materials across the plotter -
I’m not sure I follow Chris..
My printer is a printer only, no rip, just straight from corel, Say I print a large design and, as in this case I want to put reflective lettering over some of the text, I cut the letters on the summa d60 and overlay them, but they’re always too small, this also happens with prints I buy in.
It could be the tracking on the cutter, it’s still on it’s original 10yr old pinch wheels, maybe they’ve worn down and as such, don’t push through as much vinyl as the machine thinks?

In the feed direction different thickness materials really need to be calibrated as to distance instructed to do and the result.
In our normal work how often do you check that a 1000 mm length has been cut 1000mm it’s probably a couple of mm out
Most plotters are accurate with standard materials out of the box only when you start jobs like yours will you notice the problem.
The roland and other print and cut machines using reg marks adjust the cut distance after laminating because of the new thickness.Load some material but but a pen in and tell it to draw a 1000mm line then measure it.
You can alter the lettering in coral or tell the graphtec in the settings
Distance traveled adjustment
If you measure the line to be 1005 mm it’s. 05% out in the X or feed direction
Across the plotter the measurements will always be correct
If you get stuck ring me.
Other thing is the measurements that show up of text in corel Inc the leading control node and to get the correct length you need to convert the text to curves to loose the node distance -
Thank you Chris, that makes much more sense now, it would probably also explain the difference of (like you say) a few mm on an overlay of reflecive onto thinner clear vinyl, for eg.
Certainly something for me to consider..
thank you!
