reading test charts/ test forms

[beanz]

Can anyone point me to the right direction regarding the different elements in the test form and how they are used...

i was rummaging through the intarwebs and just ran into this one article by ken rizzo..

for example:
star targets - fine dot at center = good ink and water balance, larger circle means over inking, so and so means slurring..
slurring doubling lines - thick horizontal lines means expansion in the machine direction, blabla...

any and all inputs shall be greatly appreciated

I'm not sure I understand your question.
Press test forms are diagnostic and measurement tools designed to determine help printers determine and evaluate the current press condition.
They typically contain diagnostic targets, process control targets, standardized targets, and standardization targets. Commercially available ones usually come with a guide (often poorly written) as to how to perform the test using that test form - the blah blah you referred to. In many cases there is an assumption that the user of the form knows how to conduct a press test, what to look for, and how to evaluate the results.
If you could tell me which target elements you are referring to I might be able to explain its function. Are you specifically trying to run a press test or are just curious?

I can recommend: http://www.fogra.org/en/fogra-stand...inting-2-48/testforms/test-forms-in-beta.html
for learning purposes, but for testing I recommend you consult an expert, and do not waste money
