Banner shrinking

Hi Martin

Yes it can do, this came up for us only last week. Mostly down to the printer heaters so I am told.

25mm over 10′ isn’t a problem though is it?

Cheers Nick

thats what the printers feed calibration is for. different thicknesses of material to be distance correct have to be calibrated.
most printer plotters are 1 to 3 mm out over 1000mm but because its small people dont notice.
it would be interesting for people to measure there next job.

if using colourrip you can enter a feed setting for each profile, should be in all rips but dont know.

i find the maths a bit difficult so the other way for critical length work is
print a 1000mm line and measure it.
squeeze or stretch the art work to compensate, there is no distortion in the finished print.

across the plotter printer it will always be very close if not correct and is generally not adjustable.

there are a some people that say because its a flat feed path what i have said is a load of tosh they dont measure there output.

Increase your feed calibration by 0.008% 🙂
