Anything added to an ink will effectively dilute the pigment load. Even if the additive itself does not change the tack ,you will have a decrease in tack as a result of the thicker ink film you will need to run to maintain the same density. If added in very small doses the product will...

Id think bible paper would be significantly lighter than 20lb.

This!!!

are you referring to the stain surrounding the black type? If so I would suggest a brisk circular motion cleaning of the plate AFTER youve removed the ink with a solvent. One you've thoroughly cleaned the black plate with a creme style plate cleaner suitable for your brand of plates I would...

seems like you've got the bases covered. Do the feeding problems occur on more than one press?

It would appear that you have some seasoned people working for you. Assuming that there are no mechanical issues I can offer a few tips but first I need to ask a couple of questions. First are you running long grain paper? Second... does it happen when printing both sides of a job, or does most...

May I inquire as to the skill level of your pressroom staff? The reason I ask this is because of disturbing trend I've noticed to promote press crews off the broom. Contrary to what many in management would LIKE to believe there still requires a specific skillset to get the job done, even...

one of the problems that ive witnessed when it comes to the introduction of something new and different, is that often agencies are looking to keep the process the same over many different publications.

when assessing the FM screening, and the images run up to max densities were you judging them based on their visual appeal only, or did you look to see how well you could match a proof? My guess would be that much more testing and fingerprinting would be needed to dial in your printed images to...

there are still a few good ones left

careful now Alois. You may be getting setup for copyright infringement.

Alois I think all the acronyms apply here. When I refer to the things that the pressman has no control over it comes down to whats on the plate. If rich blacks total dot percentages approach the 300% range I think your flirting with disaster under many scenarios. The point of most of my rant...

The additional 2 lines was not a test to see if your paying attention it was an edit gone awry, that resulted in a second post.

Its my strong belief that every once in awhile management needs to humble themselves enough to step out of their roles as managers, and try to see themselves through the eyes of their employees. I dont know you or your company Curiosity, but I will say that ive seen the following enough times...

I can assure you that if your pressman knew what TID was some of them would be holding you to it if your company deviates too far from industry standards. I say some of them because there are always a mix of sheep in with the batch of leaders. Its the sheep that just blindly OBEY and take the...

I still place an inks ability to dry pretty high up on the list.

Luke conventional inks with a drying package are still available and actually preferred if your printing sheetfed on uncoated paper.

cylinder thrust bearings?

in commercial printing it is not at all unusual to see some rich black builds come in at a totals approaching 300 %. My feeling is that you MIGHT get away with that zonally total ink, if your at the very least inline coating the job, and if you have strongly pigmented ink. It should go without...

Ok im going to address both Eric and Curiosity in this one post. First Eric... I dont feel that packaging printing is the best example for safely running thick ink films. The reason being is that often, and I stress the work often, packaging printing consists of mostly PMS colors or custom...
