A client needs to print his images on a Xerox IGEN printer (don't know what type). I want to output sharpen the image for him specifically for this printer with Photokit Sharpener.
They demand 300ppi, CMYK images (iso uncoated).
What kind of printer is this Xerox IGEN? A Halftone printer or a Contone printer?
Product information here from a current IGEN printer. (http://www.xerox.com/digital-printing/digital-printing-press/color-printing/xerox-igen3-110-90/enus.html)
Since they (Xerox) talk about LPI on the website, I guess a halftone printer, but the employee of this printing service talks about a laserprinter, I think this is contone....

Dry toner it says. Electrostatic printers (Xerox principle) usually print images with halftone screening. I guess the 300 PPI is a bit on the optimistic side given the screening LPI possible with 600x600 dpi 8 bits. But they may want to enlarge them.

Thank you for your answer.
What do you mean with 'a bit optimistic'. I understand the optimal resolution is 2 x LPI. So I guess they use 150LPI on this printer, or am I wrong?
The image (on a card) will have a dimension of 10,5 x 7 cm (4.1 x 2.8 inch).

You would use Halftone in PKS (contone is for devices like a Lightjet, Lambda, etc).

Forget that remark, I usually do the conversions to metric on the fly (my head) and thought that the 150 LPI on 600x600 DPI 8 bit was a bit high for an electrostatic printer. Meanwhile I have seen that there are higher DPI and LPI numbers for different IGEN models so the remark doesn't have any practical value for you. There's a stochastic screening available for IGENs too.
