Press Release Summary = Discuss about paper characteristics, printing quality with
paper thickness, laser printer’s setting and testing result for photographic
Press Release Body = The market share of color laser printer is growing every year
and there are more and more people use laser printer to print photography. Almost
people focus to the performance of laser printer. After all, it must present the
printing with paper together. Let’s use different view point from paper to discuss
photographic quality by laser printing.
Paper thickness and color saturation:
The most critical is color saturation of printing image. The color calibration of
laser printer is based on common paper (80~100 gsm). If it is more thickness (for
example, the paper of conventional development system is over 180 gsm), the color
saturation will be reduced. How to increase both of paper thickness and color
saturation at same time? The best way is going to slow down printing speed and
improve physical characteristics of paper surface at same time.
Slow down printing speed can takes more time for toner transfer to get better color
saturation. In the market, there are different types for 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.
Many people recommend inkject 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.
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 charge on the paper surface
and conduct more toner to paper surface.
Due to toner is dry powder in natural, the paper has no connection with resolution.
The image resolution is decided by printer’s engine and printing language. 600 x 600
dpi can offer remarkable picture image quality. 1,200 x 1,200 dpi also improves more
grades of gray level and better cubic effect for digital printing oriented from
The next generation of photography shall have more features such as the material of
paper meets environment protection, good hand feel, without turn-yellowish for long
term exposure in air or under halogen lighting, tear-proof, no releasing chemical or
medicine smell, wet-proof, instant printing and so on.
The testing had done with HP CLJ 2500/2550/5500, EPSON Aculaser 900/1900/4000 and
Konica Minolta magicolor 23xx. That means it is compatible to different printer’s
engines for different printing speed, dpi, toner, fuser temperature and so on. The
name “Laser Printing Photo Paper” is going to knock the door to photographic
printing by laser printer.
