if you dont mind sharing, what printer are you using? your results always look incredible.
many thanks for the "incredible" ... though I guess it's a little bit exagerated
I print on a RICOH IM C4500 ... professional printer we have at the office that can print natively up to 1200/1200
After years of trials on different printers I think that printer's quality is just part of the algorithm, the only "mandatory" fact beeing that you need to print 1200/1200 NATIVELY and not through interpolation (almost all 600/600 printers can print "interpolated 120/200).
Every printer owns it's specific drivers and the REAL definition (what you really get when you print) depends on drivers.
With some printers you get better results using designs with a much higher definition than the native printer's capacity ... with others yuo'd better use lower def designs ...
With our old printer I got my best results using designs at 4000/4000 ppi.
With the new one the prints became "blurry" so I had to redo my designs at 2400/2400 ppi.
BTW ... all my designs are vectors made on Illustrator and I print using Photoshop.
So it's all a story of trials and fails and success ...
You first need to get a printer than can do native 1200/1200 ppi without any interpolation then the trials start ... 2400/2400 design, 4000/4000 design, sometimes 600/600 designs if you want simulate some aging while printing.
Depending on the quality of the drivers you will have to make a really crispy desing or introduce some "blur" on it to get a "perfect" result.
Another important thing is the color mode you use while designing and printing ... I always use CMNJ mode and my "black" evolve between 80/4050/100 to 80/80/570/100 depending on the result I want to get and, of course, the printer's drivers as I always let the printer determine colors on Photoshop.
Starting from that, and after filling your wastpaper basket with a huge quantity of film-free sheet
(yes ... result depends on the paper too so all my print tests are made on the same paper I will use for final work) you should get pretty crispy results.
