Mate I'm a press operater running a brand new multicolour, and nothing gives me the sh--ts, more then the fact that the company can afford such machines, but doesn't want to back it up with a proofing machine /densitometer and all the simple nescesities that should be available for the...

Dwane,, not sure if your roller layout is similar to our press , but instead of taking all the rollers out to check form 2 and 3 too oscilator you simply take out water form and 1st form that way you can see the 2nd form too oscilator stripe easy. Same thing goes for checking the 3rd form to...

You want the metering rollers to be around 20 -22 shore hardness.. for low to no IPA printing that way you can still run a tight nip, but the lower viscosity fount can still make its way through the nip + there generaly more hydrophelic... were as if you had a harder metering roller but the same...

Dwane, I'm guesing these water marks, are of about a 1mm thick line across the sheet? Is it hapening anywhere on the sheet, or if you were to measure the diameter of the water form do the lines roughly line up from that distance from the lead edge of the sheet? Do a calcium flush, this should...

Alois, your correct, seems I got it the wrong way around IPA water miscebal NPA Solubility: Infinitely soluble n-propyl Viscosity (20 ° C) 2.256mPa I'm just wondering if your running IPA at 5% with a 2.86 cP at 15 C viscosity, would the fount still be more viscous then running with 8%...

Nothing wrong with that, if you dose it midway between what is recomended, you have 8%NPA and 2% actual fount being dosed in automaticly out of one drum There is no need then to have IPA on the premisis which as you know has an extremly low flash point,, The flash point of neat NPA is much...

John, I understand the original poster is more focused on the enviromental side of things, but below is his post just after your first reply. Also this 2 in 1 fount has a vapour pressure of 10mmhg @ 20c which is on the low side. I believe that the bonus of using this stuff on poly plates is...

We have recently started using that 2 in 1 fount, and we are simply blown away by how well it works, expecialy on polyester plates. Its set to dose so we get 8%NPA and 2%fount which emissions wise roughly equates to running IPA at 5 -6 % We had trialed numerous founts ranging from your IPA...

Yeah of cause there are going to be mistakes here and there,, but when it gets to the point we are seeing it's just a great waste of time and money, due to someones lack of quality control..... If a press man was to leave wheels in the print area and it marked , or have scumming up or a lack of...

The figures I have worked out, I can still make money sending CMYK work to trade printers,, example : I can get short run say 1000 cards done out side for $50 - $60 then I still have room to put my bit on top. Which is basically all I want. My main focuss will be PMS colour jobs What I print...

Unfortunatly I know what its like to be going through what you are at the moment.. I've noticed that ever since we have gone fromg the old style of making plates which was years and years ago to the ctp style and every thing on computer's more mistakes are being let through.. We have had to re...

I am looking into starting up a small print business, we would be aiming at general business stationary, ranging from Business cards / Letter heads / flyers / envelopes / NCR books.. etc Any full colour work would simply be sent out and printed via a trade printer as we don't have the funds...
