I worked for a company that had a couple of offline film laminators. I would often ask the operator to take a freshly printed sheet and run it through his machine just to get a little preview. Of course with a color as you mentioned it would be doubly problematic because of the way a color...

I've found that very often, promotions have less to do with abilities, and more to do with a guys willingness to take abuse from upper management. This I call "yes man syndrome".

Alois, If you were to re read my post you will find that I offered the suggestion to dilute the strength of the yellow ink only as a test to accurately trouble shoot a problem. I never suggested that you do that on a regular basis. As a matter of fact I followed that suggestion up with...

AWW shucks!!!!

Those were the days when men were men, and sheep were afraid!!! Not trying to date myself here but I have fond memories of learning the craft of printing on similar vintage Harris, and Miehle presses

I think there is a common misconception among many pressman, that in zones with no ink coverage, or in zones outside of the paper perimeter. ink keys should be shut down to zero ink feed. This thinking is wrong. You need to always feed a little bit of ink. The amount to be determined by the...

Not an Anicolor guy but my guess is that the water feed is just a number that is influenced by many variables. The first and probably most influential variable would be the settings on the rest of the dampening system. A tight metering of the Alcolor system would would require a greater...

Have seen this scenario played out more than once. Its a shame that some companies will take a big dollar chance on the unknown, when they have tried and true employees right under their roof working for peanuts. The veteran employee should consider this as job security. Rarely do the high...

The amount of paper needed after making color corrections on press varies. The biggest variable in my opinion is the amount of coverage. Its a common misconception, by many people in management, that heavy coverage requires more sheets for color makeready than light coverage. This is not...

Regardless of the offset press, and regardless of the closed loop system you are using, I agree with Eric, in his statement that 10 to 20 sheets will not be enough. The press needs to run enough sheets to establish as Eric describes as a steady state condition. On a form with a large amount of...

My suggestion for a light spraying of the rollers was made in order to avoid mixing anything into the ink fountain. The anti skin spray would offer a temporary reduction in tack, in order to get the press started without the delamiination taking place on startup. Ive found that if you can get...

Alois I only found when because I didn't bother to look past the first page. The one that I did find made the point I was looking to make.

this goes without saying when possible, but there does come times where you have to make due with what you've got. This is especially true these days when the temptation to increase profits by buying crap paper is more prevalent than ever before. It still amazes me how some printers who like...

Im gonna go out on a limb here thaiha and guess, based on the pics you attached, that the problem your having is for the most part BEGINING on startup with clean blankets. In an attempt to avoid reducing the inks whenever possible, you may want to try starting up with reduced tack. To do this I...

Alois, What you refer to as a witch doctor remedy has proven itself to me countless times. Now I suppose that if we were still operating in the days, where all the time in the world was given to getting a job to run at its very best, then the needed time spent to swap out a blanket would be time...

Alois, I find it a little hard to believe in light of your chosen name on this forum, that you would trash an old school remedy that has proven itself effective in achieving a quicker release from a blanket. Perhaps your vast experience in pressroom operations missed out on that lesson. Not to...

no doubt crappy paper, but thats about the norm these days in many places. As mentioned lower tack inks, less pressure. `The quicker release of the blanket can be done on selective units. You can even improve blanket release in specific areas of the blanket by wiping the corresponding areas...

Is there a particular post you are referring to alibryan, or are you casting a wide net here?

A small change in fit is to be expected after washing blankets. This is one of the reasons I find it so important to run minimum spray powder on the first pass of a press run. Avoiding blanket washes and production interruptions whenever possible, will give you the bast chance of color and...

Gordo, when you say 300 to 320 are you assuming an inline aqueous coating with traditional litho inks? Without an aqueous coating its my feeling that your flirting with disaster to run TID that high. The biggest issue I have with that high of a TID is that when the inevitable offsetting...
