Does anyone know if there is a printer in southern Ontario that can print UV inks on wood (hardwood boards)? Google doesn't, but I find that hard to believe.

That's right, one of them. The bearer on that press are kept much cleaner and checked regularily now.

There must be other factors involved I don't know about. We had three experienced press operators (80+ years total) a Kodak/Plate/Press technician (ex pressman) and myself do a number of roll-ups with Sonora plates a few weeks ago. Clean blankets, new fountain and ink. On the first set-up the...

It is natural and understandible that press operators should assume someone without hands-on press experience does not know enough to solve press issues. That is a logical and safe assumption. The other side of that coin is… this press operator does not have, nor are they willing to consider...

Thanks for all the posts. I 've been away and not getting any updates recently. The problem is, as a few have mentioned, over-emulsification, or water logged ink. The ink begins to show microscopic drops of water, then soon after that the water begins to carry microscopic drops of ink that...

Using Kodak Sonora XP, on press develope/cleared. The same plates will produce excellent dot after problem is fixed. It is a press problem, operational, not mechanical.

No Title I will share it shortly, I was hoping for a few more people that know to jump in. Here's another sample of the problem as it progresses. bottom image is @ 25% dot

Thanks to everyone taking the time to suggest solutions. I should have phrased the post more clearly. The problem is something I think is well known and easily identified (with a scope- thanks again Gordo). I have seen it many times and explained it to operators who've then fixed it. My purpose...

Same operator We will work together.

Assume plates, chemistry, pressures, ink the same.

#1 and #2 are 45% bar on jobs run on same press, K unit within a few days of each other. Same stock, same side of stock, same bar, same CTP, same plate brand. We are having a disagreement on the cause of this and I've been asked to get the opinions of professionals without my opinion so...

Try this... Dear new client, please sine the following contrakt: We, your printer, have full athority to pull your work off press, or stop its praduction at any point it is in our posession, with full costs incurred to be payed by you the client, whenever we sea something we think is not correct.

Not sure what you mean?

Beginning to suspect the operator/s are not as familiar with the press a they claim. SOPs will have to be discussed and reviewed regularly from now on.

No Title Took a photo of the Cyan unit operator side bearers.

Trust, but verify! So, it seems the bearers were squeaky, mirror like clean, because apparently they cleaned them when I asked for the ink-transfer test. Before cleaning they were solid, dry ink on plate and blanket bearers.

Are there any standard practices that decide when to shingle in, or out? I have a reasonably good knowledge of the mechanics, but would like to know if there are any things to consider that I haven't thought of.

The plate/blanket bearers are shiney, like a mirror. I should have said 3mil pressure - plate, blanket packing minus undercut. I guess what confuses me (I don't know enough about it) the bearers are not bearing. I thought the bearers were always touching slightly and the plate/blanket presser...

Just finished a few hours of testing this morning. I haven't had time to analyze all the sheets yet. I'll post those results when I finish. One thing that surprised me, we did the ink test on the bearers and got nothing with impression on. I would have thought there would be some contact, no...
