Post this in the sheetfed forum. This is a prepress forum

The book is pretty easy to understand on setting the rollers. If you get them to spec most of your issues should resolve themselves. Make the form to oscillator around 3.5. mm and the form to plate 3 mm. In the picture it looks like the ink is piling on the rollers. An oz of alcohol sub per...

We have 3 7800 indigos and 3 10K indigos. Starting up is a challenge. Service in our area is awesome plus our phone based support is very good. Biggest hurdle is getting an experienced operator. We are trained constantly to become mechanics and operators. I am level 2 where my three 10000...

The Violet and Orange are not considered spot colors. It is what HP calls indichrome. With violet and orange you get a much better color gamut and are able to get closer to a lot more PMS colors then you can with conventional 4 color. You can hit PMS 165 and you can get a lot closer to the...

The Quickmaster or the Printmaster will give you a better dot then the ryobi 3302 or an AB Dick. As mentioned before it is the only one that is a Bearer duplicator. I have been able to print specta dots that go to 20 micron but in order to do it a lot depends on the condition of the press the...

Check the spring on the gear side for the plate eject. It should be 5 mm.

The worse thing you can do is leave them under pressure. I always took the meter roller off the units I was not using. Even so I was lucky to get a year out of them.

We have 2 HP10000 and 2 HP7600. Because of the volume and the importance of getting machines up and running HP has provided us with a conductivity meter. The boards in the ink tanks I believe is the LCS board or the ITS has two plates of some kind of metal that measures the conductivity of the...

It is more about the amount of press wash used. Too much wash and the ink slings off the rollers before it can get to the clean up trays. When ever I had down time I would pull all the rollers and clean the crossbars and the roller ends. The best time to do this is when you are going to run a...

The sub is not going to hurt you. The dose is so low it will not change the wetting ability of the fountain solution it just help liquify the ink build up on the meter roller so it can get back into the press. The piling got so bad on our press we could scrape ink off the meter roller with a...

Best way to ink the water system is to ink the press up put an old plate on the plate cylinder and bridge the ink with the plate ink forms and water forms. That will get you a better more consistent ink flow. This is the best way to clean the press as well. Take a bottle of water and mix it...

We ran some 350 gsm but I would not go to 400. 350gsm has to be grain long and you still will have issues of scratching especially if it has a perfector. Ours was an SM 52 and I would imagine the bigger the press gets the worse the problem will be. That press is only rated to go up to 350 gsm...

Put a different dampening system on the press. Crestline or compaq. In the long run it will be your best choice. We used to have to maintain almost 25 percent alcohol with our super aqua.

Are you talking about the pump that provides the vacuum for the feed head and registration board? If so the pump should be under the catwalk near the chiller. It has 7 vanes in it. The Heidelberg ones are real pricy but you can find them local for around a hundred bucks. It is pretty simple...

If you do find the correct paper you will also need the correct coating. Nycote carries this.
