alcolor

Hello everyone, I’m thayiP from Sri Lanka. I’m currently running a GTOZ 52 with a conventional dampening system. I’m trying to replace the dampening cloth rollers with rubber rollers. I already made new 53mm rubber rollers, which match the diameter of the original dampening rollers with the...

Hello, good morning. My name is Andres, and I’m writing from Argentina. I am using an AI to translate this, so I hope the technical terms are clear. We recently acquired a 1991 Heidelberg GTOF with an ALCOLOR system. We are having trouble calibrating the dampening unit because we don't have the...

Hello. We mostly use water dampening Heidelberg machines in our country and I am not familiar with other dampening systems. I want to buy SM 74 and SORMZ machines which mostly are Alcolor, Compaq, Alcohol dampening systems. Can anyone help me know what chemicals such dampening systems require...

I have a MOV with a Alcolor system and every time the green production button is pressed and the damp units go on impression it looks like a roof without a gutter as the water (9 degrees C) pi€€es down and into the drip trays. Can anyone she'd some light on this problem? It's only the first 3...

Hi Heidelberg people. I am currently running an M.O., and the book is a little confusing when it comes to striping the alcolor rollers. I've done installation of a new water form on one of my units, and after striping the rollers, I often get a "double" stripe when I drop the water form to the...

i need to know the differences between Alchohol dampning & Alcolor dampning? and Which system is better? and Thank.

Hi guys Can anyone instruct me on how to calibrate the alcolor on my 1995 sm-74 to marry up to correct hydrometer reading . Hydrometer reads 10% Cp tronic will display 6.5% i cannot find the technotrans manual. P.s I have tested alcohol with 3 types of hydrometers to be sure. Regards...

Hi everyone, I've been here before trying to solve the same problem. We got this new machine and since i've had problems with dampening. The problem basically is that i get more water in the center of the plate than in the edges, so, i use less water=scumming in plate edges. I use more water to...

Hello every one, I just replaced the pressure regulator of the pneumatic system on the above machine. It now keeps a 7 bar stable pressure but something might have gone wrong because now the compressor does not turn off. According to what i can remember, i would turn machine on and some 3...

I operate a GTOZS. Since day 1 I havent managed to print well because of the instability of the dampening system. I concluded to the following: I replaced all rubber rollers - inking and dampening - adjusting everything by the book. I use alcohol free solution and water no Ph additive to my...

I have this strange problem. The alcolor motor on printing unit 2 doesn't slow to the preset or when pressing the minus dampening button. that had happened before but I switched the controlling cards from the 2 units in the electronics cabinet and the problem disappeared. I did the same but no...

Hi, Does anybody know if there is a temperature you MOST keep in pressroom to operate an Alcolor press? Right now im at 86 and water distribution on the plate is very unstable. Any advice? Thanks

I'm working first time an alcolor GTOZ. Took all the alcolor rollers away and put them back together trying to do it acording to manual. Only in my dreams it was easy. I can't get it to distibute water evenly in the plate, but my biggest problem is that i have a 3" water stripe coming from...
