Toner getting smeared at the post office

[teclighting]

Thank you to those that had positive things to say about the Tec Lighting product, it means a lot to both Tec Lighting and myself.

I would like to comment on the safety of UV.

1. All of the UV coatings offered by Tec Lighting are 99.9% VOC free.
2. Paper that is UV Coated is recyclable.
3. The only by-product of the entire system in operation is small amounts of Ozone that can be easily vented into room with ample airflow or out of the building.

A great article about this was written by Gary Cohen
RadTech North America International. It's very informative.

If you have any questions please contact me at info@teclighting.com

I have a canon c6000

You can try to turn up the voltage through "Paper type management"

You will need to make a custom sheet.

You could also try "register paper" and pick a "heavy 6"

Both of these will "turn up the heat"!

I just finished doing a bit of consulting at a direct mail plant. The toner from their laser printers was tracking and smearing on their sheeter-folder lines. This happened with only some jobs, and on those jobs, only on some of the paper rolls. That's interesting.

I did improve their bindery equipment and make it less abusive along the way. The toner-paper interaction problem demanded resources they were/are not willing to commit. However, it looks like the paper fibers on some rolls are more likely to break loose, and the toner stack with them. Too, they are using old equipment, reconditioned printer drums, and high settings to compensate for that, so the toner stacks are prone to breakage, anyhow.

As it happens, some paper is too porous, and some paper is not porous enough, kind of like Goldilocks' story. It's, well, a bear to deal with.

That letter "a" is 8 point.

Yes, it will happen with an iGen, Indigo, Nexpress or any other digital device. UV coating is about the only fast option... You could varnish the sheets on an offset press but then you will need drying time. You have to seal the sheets.

I bought a 25" UV coater (without the feeder) relatively cheap from Tec Lighting (Tec Lighting). I ran a shop that had two HP Indigo's and this machine suited them well and my customers where happy. I would buy another one in a heartbeat!

I am glad to hear of your positive experience with Tec Lighting units. Call me when you're readey to buy another unit.

You can help your toner stick harder to the page by using the Gloss setting in the paper catalogue.
Setting the Gloss to +2 will ad an extra 30 degress to the fuser temps. This will help the toner stick to the page better.
The best solution is still UV coating

We've had great luck laminating KM toner with standard gloss laminate. It's amazing how the post office insists that you conform to their inadequacies instead of them updating their equipment to today's standards.

Guys (girls too) it's ABSOLUTELY not a problem of toner STICKING to the sheet. It's a matter of friction from the USPS mail sorting machine PERIOD! It effects almost every type of printed piece (digital and litho). The UV coating simply takes the abuse saving the print. Take time and go through the mail, look at both sides of the piece.

Karl, We actually use coated 7 paper type in the 7000 and in fact because of the paper we use (300 GSM glossy stock), we have the secondary voltage turned up to 6. It still rubs off. I completely agree with Craig. It is a post office issue. We complained so much o the post office that the manager invited us to come to the local bulk mail facility. I actually went there along with my production manager. We took samples that they ran through the mail sorting machine in front of us. The toner rubbed off every single piece. Their reaction.......they just shrugged and said we need to coat our pieces or start sending letters. The guy who ran the pieces through made it very clear that there was nothing they could do and seemed irritated that we were even there.

Hi all,

I am sorry if this is not the right place but I was curious on how everyone handled the issue of toner getting smeared when it goes through the sorting equipment in the post office.

I know digital printing in general has this issue. However, is UV coating the only solution. Not only does it add significant time to the turnarounds but it is also not very environmentally friendly.

We have a Canon 7000VP and we do have the issue of the toner getting smeared on the postcards when they go through the postal system. It is random but it does happen more than we want. I know other printers in the area who have IGENs and they have the same issue as well. I am assuming that most digital printers have this issue.

Most of our stuff is run on 12 pt. glossy stock.

Thanks.
