how to lower the temperature of baking or printing on a laser printer?

Question

Iron

Problem: glossy sheets melt on which the image has already been applied.
It is necessary to apply more inscriptions on top of this image.
Can anyone advise a printing house
that can do this?

Answer 1

In short, the conclusion: glossy leaflets, on which something is printed with solid-state ink (fast printing in printing houses), may swell in some places when heated to a high temperature. It is treated by the fact that the leaflet is carried to the same printing house,
which will print everything that is needed with the same solid-state ink. Since the heating time
is not so long, due to the speed of printing, there will not be time to swell there.
Something like this.

Answer 3

I was helped by the choice of paper type in the print settings ...
