the 8 in this discussion is 8 levels not 8 bit. it can be achieved by controling laser start stop in between the pixels on the scan axis, thus creating more than 600x600 combinations of area coverage. or it can have 8 drop sizes in the inkjet case. any of the above is done in the imaging...

the images are misleading. the human eye will not see all those details but an integral of the very small details so the difference will be less appartent if at all. in addition laser dots are not separated so that the surfaces and dots look much smoother. EG

Just changing angles will not work. some letters are slanted or with serifs and you come back to square one. you may try shifted angles by 7.5 degrees (old scitex style). beware that you should keep the 30 degrees between the main colors c,m,k and 15 for y. if you put the black on 90 or 0 you...

Gordon, thanks for the very learned explanation.in my opinion the phrase " keep it simple" is worth sacrifying the 100% accuracy . indeed it is only 80% accurate but works for most cases and VERY VERY VERYSIMPLE. regards EG

to make it simple: calculate the amount of combinations of pixel values . the higher the better. the equasion is: Xdpi * Y dpi * gray level#. thats it ! but, this formula assumes that the printer vendor makes all combinations usable. if the dot or spot is too big when you print 50% you might...

back to media back to media well the single direction was just a test to do. if you did it and there was no change I must refer you back to media. If media advances differently along carriage travel you will get this banding. So try a better media that is well attached to the rolls of the...

Atmospheric plasma treat Atmospheric plasma treat this plasma treat is a proces used to treat plasstics befor ebeing paited. it changes surface energy dramatically. not cheap and can be build to suit your needs. try Website: Plasmatreat - Openair® plasma technology – surface activation. or...

could it be as simple as using jpeg ?!

if you want to keep the paste with bidirectional printing try tunings the lamps to equal power. lamp power differences will create gloss banding even in high quality modes. :)

Regardless of the real reason or source of problem. to eliminate the possibility of " left right" banding try printing in one direction and if problem dissapears then we can start asking why. if they do not dissapear check for inkjet head functionality- nozzles and alignments. please whatever...

a different approach to varnishing a different approach to varnishing there is an israeli company that is working on non impact(inkjet) sheet to sheet varnishing machines, full flud or spot. worth considering as a long term solution. Scodix is the name, look them up on the web or ask me for...

try calibrating the printheads. do the full calibration procedure. afterwards verify that you do not limit the ink too low ot too high in any of the proceeding color calibrations and profiling stages. hope it will help.

why compare only oce to anapurna. there are many others in the market giving 3m wide format and flat bed option.Matan Barak3, jeti, zund...

did you check if media advances properly during printing?it might also cause banding

UV Gloss Banding UV Gloss Banding Uni directional is the solution. multi passing will eliminate gloss so beware. i would also recommend doing a linearisation ink limiting and color profile using the same mode of printing to avoid color problems.

Wasatch SP has capability to print separations using black, that is for sure ! My original question (see up the thread) for this discussion was how , if at all , can I configure other colors rather than black, instead. As of print quality using epson 7880 (not 7600), a correct selection of...

ctp ctp try VIM Technologies, Home Page browse a little and you will find an explanation. they use epson original ink or www.glunz-jensen.com they use epson print engine with their own inkjet liquid instead. enjoy eg

Well, both ! good poliester for the shorter runs and metal for medium runs. sometimes cheap is advantegeous over un-neccesary quality.

can the wasatch rip be configured to use magenta as the ink for ctp as you describe?is it a simple setup in the wasatch or an extra s/w needed?
