LUX light for printing

[Garnick]

  HELLO AGAIN FOLKS

  I'm just getting back into printing on my EPSON P7000 and it's becoming a bit of problem, being away from the printer for a long time and the mental problems now.  However I'm slowly getting back into the work.  The one thing that I'm not sure of is the lighting for the printing and the PRINT it's Self.
For many years I've been using LED Lights and they have done a great job for me and my customers.  I've just bought a Light Meter which will tell me the LUX of light.  Now the problem is that I don't know the many LUX I need at 4 Ft. from the lights and the print. I hope I've written this so that you folk will be able to read it and perhaps give me at least some sort of a number to get started again.

THANK YOU ALL!!! And for me it's great to be back into the FORUM again.

According to ISO 3664, for critical comparison (P1), 2000 ± 500 lx and better in ± 250 lx. For practical appraisal of prints (P2), luminance should be 500 ± 125 lx. 500 lx is about average bright office lighting.
