How to print photography by laser printer!

Archived from groups: comp.periphs.printers (More info?)

The installation of color laser printer is growing every year. More and
more people use laser printer to print photography and disappoint in poor
printing quality or paper jam. What is problem happening when using laser
printer for photographic printing?

Paper thickness and color saturation:
Basically, the color calibration of laser printer is based on common paper
(80~100 gsm). If increasing photo paper thickness (for example, the paper
of photographic development system is over 180 gsm), the color saturation
will be reduced. How to avoid loss color saturation when increasing paper
thickness?

Printing speed:
Slow down printing speed can take more time for toner transfer and
increasing color saturation. In the market, there are many different types
of different printing speed such as 4~5 ppm (pages per minute), 16 ppm and
over 20 ppm. Fortunately, printing speed is possible to be controlled by
selection icon of paper material. Recommended speed is 106~160 gsm.

Thermal stress:
Many people recommend glossy photo paper or premium paper for laser
photographic printing. Be careful! The heating temperature of fuser can
rise up to 200 degree C during printing. The potential risk of thermal
stress is possible to melt-down the coating material of paper surface or
crack happening. Particular, printing is operating at low speed. Thickness
again! The thickness of those products is over 80~100 gsm.

Paper polarity:
Another methodology is how to change physical characteristic of paper
surface to improve toner transfer. Fortunately, toner is negative polarity
of almost laser printers, it is possible to spray electrical positive
charges on the paper surface and conduct more toner to paper surface to
increase toner density and color saturation as well.

Resolution:
Due to toner is dry powder in natural, the paper has no connection with
resolution. The image resolution is decided by printer engine and printing
language. 600 x 600 dpi can offer remarkable picture image quality. 1200 x
1200 and 2400 x 2400 dpi will increase more grades of gray level and
improve better cubic effect.

Glossy:
Keep in mind! Toner is dry powder. Whatever your paper is high glossy or
brightness, the surface of photo paper is covered by toner after printing.
If it can present glossy, that means the toner density is not enough and
the color of printing quality is very light. Actually, toner embraces wax
inside and it can offer brightness after printer.

Moisture:
Moisture tends to make pulp fibre expansion, raising paper thickness and
uneven roughness. Coating skill perhaps is one of solutions to isolate
moisture in air. Apply synthetic paper to replace pulp paper is a good
alternative to resist moisture completely.

Testing:
We invested over four years to study how to avoid loss color saturation
when increase paper thickness and overcome high temperature heating
problem. The testing had done with HP CLJ 2500/2550/3700/5500, EPSON
Aculaser 900/1100/1900/3000/4000, Konica Minolta magicolor 23xx and Xerox
DC12. That means it is compatible to different printer engines for
different printing speed, dpi, toner, fuser temperature and so on.
Meanwhile, it also does not need to storage in temperature & humidity
controlled room.

Low end printer:
Such as HP CLJ 2550L, the price is around USD 500, 600 x 600 dpi printer
engine with PCL 6. The companies of recycling cartridge & refilling toner
can help you to cut 20% of consumables cost.
