We use FM with 2400 dpi.
We use FM with 2400 dpi.
IN CHINA, most factories use 200Lpi AM, 2540dpi, Dot Shape:Euclidean.
Rare ones will try to take FM.
Offset Printing :
Normal commercial printing - 175lpi - 250lpi
Packaging prinitng - 150lpi - 200lpi
Quality printing and easy to print - Hybrid screening, eg. Kodak - Maxtone MX, Screen - Spekta, Agfa Sublima etc.
Special product or quality control - FM Screening
OK - we used 200lpi at 2540 dpi - kodak maxtone 30y - round
But what angel you people used ?
The best screening for me is the hibrid tecnology!
beacuse the traditional is the classic point, the new FM is only for very good machine and not all users like there point, he is see from more users like a laser printing.
my personal opinion is that the classic is the better, but the yellow with FM screen give very luminosity at sheet printed, always printed with good machine.
General print with AM screening, some fine products will be FM, there is more than one spot color will also use the FM to prevent moire
General mainly on AM , especially good quality printing factory packaging printing some FM and mixed
and for screen printing what is the best screening?
I use always AM but if there is a solution to eliminate moire please tell me.
With our inside AM
Prinect mix 250lin
If you are using a CTP of violet technology, it is not recommended to use FM, only a variety of hybrid screening, it uses FM screening in highlights and shadows, and AM screening in halft.
This solves the problem of stability in the reproduction of higher LPI, as 175lpi or 200 lpi.
if using thermal CTP technology. values depend on the type of laser used thermal, most uses laser diode array, and others use GLV, but only , KODAK, use GLV SQUARESPOT.
all thermal CtP, except SQUARESPOT, generates a Gaussian point screen, more or less than each other, but of significant importance.
that is why, that companies have trouble of recording raster point, use a variety of formations special raster point, to try to solve with software, the defects of recording technology.
only the laser thermal CTP SQUARESPOT propiety of Kodak, is capable of doing FM and print your result is as theory suggests it should be.
more even. if used FM with SQUARESPOT. also requires naturally a calibration adjustment of the gain of the press point. and after that, the plaque and prints are more stable than those of AM and may even extend the range of offset color reproduction and reduce ink consumption. making impressions less sensitive to variation in ink density media, giving total control of printing and prepress truck doing less sencible to do the mauinista of the press.
FM raster gives better results on pictures with lots of small details but needs to be really precise calibrated, otherwise it would give "dirty" and "smudged" result.
We are currently using FM 10 microns. It is a big struggle when our exercise for FM screening started. The results of FM were compared with AM 250 LPI. The results initially too bad to drop the FM screening in total.
But when we analysed the problem, we found it is more an issue in color profile we use. We created Device link profiles for our press using heidelberg color tool box and we compensated dot gain accordingly.
You don't believe the results we attained. Our printing is currently admired for the quality and customers are ready to pay more for our quality job.
We advise use FM 10 microns (may be second generation) with right prepress profile and corresponding dot gain curve. You will see a big leap in your quality of printing.
