Magenta 15 - 20 % Cyan 14 - 19 % and Black which is from carbon Black 20 - 24 % and depending on the condition, 5 to 10 10 % Reflex blue flush The pigments are dry grind percentages. Engin

Hi everybody, Depending on the color strength these are the ranges for offset inks: Yellow 9- 15 % Magenta

Some additional notes: In the previous TVI curves, there was 3.0 % increments at 40 %, now the same but at 50 %. When 12647-2:2013 came out, the b values of the papers were announced as -4 for both coated and uncoated papers but in reality they were much higher in the industry, the coated paper...

Hi, Can someone share XMF Colorpath user guide in PDF for me? Best regards, Engin

Thank you very much it is good

Thank you very much Alois it is good

Hi everybody, The system here is heat set presses where the inks are being pumped from a stationary storage tanks. My question is as below: Is there any Ink amount control system to be pumped to each press? Does anybody have any information about it? The aim for this is to connect the pumping...

For the agressiveness, now understand, is quick drying on the rollers, but the formula should be ajdusted accordingly otherwise will not be used as a duct varnish, to aid this you can ask them to supply to you a glycol type retarder which reduces the drying speed on the rollers before it reaches...

Monsun is containing permanganate type salt which is called as water active dryer ( which is co-dryer of oil based foils inks and IML inks), when comes into contact with water ( here the varnish absorbs water while on the plate by 15-20 %) and this water acts with the permanganate compound to...

Dear Cemetary, I do not understand by non agressive you mean. water based OPV's, are containing ammonia to balance their pH the only aggresiveness comes out from this to disturb the non-alkali resistant pigments if there is in the print, behind this they are drying very quick ( about in 10 sec)...

Just one more suggestion, may you can use water based opv from duct instead of oil based opv which gives more gloss and quick drying. regards, engin

OPV - over print varnish I know you did not add extra siccative, I said adding excessive siccative into the system reverse the oxidarion reaction resulting in poor drying instead of accelarating, also yellows in non inked areas of the surface. Cobalt now in EU out of use, and mangan dryers...

Another example, which shows much more better that the corresponding densities against ISO12647-2, dE and tarnsfer amounts. regards, engin

One solution may be, if you have a proofer like Orange Proofer and a sensitive weighing balance of 0,000 digits, try to make dry proofs by weighing the transfered amounts of 5-6 proofs on a coated paper that you think standard for you, in my experience CMY between 0,5-0,7 grs/m2 and for black...

What me and Dan suggested is a temporary solution, it is an aspirin since you have an headache, the best solution is the ink supplier should investigate on the press and should change the formula of the ink according to his observations since they have the ink chemistry and should do whatever...

Dryers aids oxidation and you feel as smell for this to follow.Here , oil based opv contains china wood oil which is the strongest oxidative vegi oil, and its smell is very hard during drying. I did not have any experience from my sheetfed customers when used oil based opv as heat generated...

Dear Dan, In Europe, fount solutions are not so acidic as you have in US. (Nowadays, some vendors tend to offer acidic F' in my region but not very common.) The main issue then is to keep water hardness under control since FS do not help at that side. Water treatment ( most commonly used in...

Mixing into the ink linseed oil or liquids not easy and exceesive viscosity drop may happen, I suggest to use gel type tack reducer containing mineral oil which sheetfed presses use,it is easy to mix with ink. regards, Engin

Here is one pdf. I hope it helps. Regards, Engin,
