no magic involved here Alois. The point I'm making as that ink heavy ink coverage is usually a no brainer when it comes to getting color. As far as water balance that usually follows the ink with a minor adjustment up or down. The point being is that its harder to control ink and water on...

if you must deal with the additional length of the double delivery you may as well reap its benefits. I myself have never worked on a double delivery press but I can see how, as Cornish points out, there may be benefits. The biggest plus that I see, is that if you can set the delivery up to...

the pattern that it follows would be a good indicator of just how many rolls.

please share your secret for avoiding this phenomenon on the occasional job, shy of having pre press image large take off bars onto the plates for every job with light coverage??? Unless of course your always running posters or full coverage jobs like packaging. In which case you'd rarely be...

Sounds to me like the paper was sheeted off of multiple rolls with one of the rolls being defective. This would account for the some good and some bad you describe.

I was the guy that suggested that you shouldn't run your ink setting on zero. And you are correct in saying that if the fountain is properly calibrated then a zero setting should feed a small bit of ink. The point I was trying to make, is that some ink needs to feed into inker, even inline with...

may want to try bringing up all 4 colors about 15 percent and increasing pressure by about .004"

One of the problems that I've encountered when printing ANY color, that has a very high transparent white component, is that just about any variable in the process, can result in problems with color matching. For example.... the slightest traces of a previous color, still on the rollers from...

I can see the patch blanket to be an absolute cure for about 250 sheets, tops. On any significant press run there will be a slow and steady build up of fountain solution until it gets so bad that the image washes out. Shortly after the washout you will begin to drip, drip, drip, all over the...

How convenient that the supplier is no longer in business. How bout a stroll down memory lane, where you share the name of the supplier???

Some good suggestions so far. I like the one about paper quality as a first check. As a test try throwing about 100 sheets into the feeder of a different stock. It should be a stock with a bit more body, and most importantly, a stock that lays perfectly flat. No wavy edges for this test...

If you need to get through this single job I would suggest finding a way to dissipate the static charge that can build on the sheet. There are few ways to do this that offer varying levels of success. A search on this forum would likely turn up the more common methods. If you print on these...

I do think its a regional thing. Ive spent most of my career in the northeastern United States and the steel roller that turns in the ink fountain has always been to me known as the ink ball, or the ink fountain roller. The reciprocating rubber roller that feeds ink between the "ink ball" and...

I too worked for a company that continued to do film and halftones right up to the mid 90s. We specialized in coffee table photography books, and limited edition, numbered. and signed stuff. Most of it was 300 line duotone and tritone on super calendared archival paper.

Id much prefer the duotone or tritone option for black and white reproduction, over 4 color black and white. Ive found 4 color black and white to be very good at laying down lots of ink, but very tough to keep neutral. Grey balance on such images require very close density tolerances, even...

I guess the manufacturer of this magical roller lube is going to remain anonymous. I thought the purpose of this forum was to share information Alois??? Either that , or no such paste exists.

so please share with the forum how you were able to print clean on a printing unit that had roller lube on the ends. Brings to mind the rare occasion when Id mistakenly ink up and unit before washing off the roller lube. I remember knowing right away, when trying to roll up the plate, that Id...

I ask once again to share the product that was able to run side by side with a litho ink and print clean without scumming? Unless of course your cutting your blanket packings to avoid transfer from plate to blanket of the scummed areas. If this was your remedy then id like to know how you kept...

I've seen no mention of a powdering unit. Often UV presses are not equipped with a powdering unit. If your press does not have one you would be well served to install one if your intention is to print with conventional inks.

were they viewing the yellow singles through a Kokomo filter. Without this filter it would be pretty difficult to see just what the yellow printer was doing?
