Printing letterheads

We've printed letterheads for a client on a xerox machine and when they run it through their printer our artwork (the artwork printed from the xerox machine) starts to bleed onto the paper... Apparently this may be due to their machine burning at a high temperature than ours. Is this correct and how do I overcome this?

 

It certainly is correct. Our toner is plastic and unless your client is using a fuserless printer - ie Inkjet, the toner will melt again and offset possibly damaging their machine. There is no fix.

The long and short of it is to print the Letterheads litho if they are going to over print them again on another fuser printer or get them to use an inkjet to overprint them

Ok.. thanks MarkD

 

Black and white lasers and copiers use harder hotter fuser rollers than color lasers.
It's amazing that the color laser toner doesn't come off when you run it for a second pass through a color laser, but I haven't had any problem with this.

 

Your customers machine may have a setting for printing on pre-printed material.

 

I've been told that if you are going to print letterheads that will run back through a laser or copier that you must let the ink set like a traditional offset press. 7-10 days before running it through a laser again. A colleague of mine has sworn by it but I've never experienced that yet. Hopefully that will work for you.

 

If run on an offset press, it depends on the ink used. I think 7-10 days is a good safe number, but there is a good chance 3-4 days would be enough. In cases where we know I client will be running them through a laser printer quickly, we use laser safe inks, which advertise being laser safe in 48 hours.

Now if your talking about printing on a laser machine, then I haven't ever heard of that. We regularly run full color work on our Xerox digital press, that will be going back through lasers, and never have had a complaint. We had one client who insisted that anything printed on a "copier" would come off when she ran it through her black and white printer. Said it had happened numerous times, yet when we ran it on our Xerox Press it didn't, so there must be some difference in the toners used among the lower end Xerox copiers and their "Press" line.
