Selected Comments and Responses

I get a number of comments each month that ask great questions – so I thought that once or twice a month I would post the question, and a brief reply, so that we could all read them without scrolling until our fingers get blisters :)

Here’s a couple, more to follow: (I have edited to keep things space requirements manageable). The first theme this month is art, and art reproduction:


(I have been told that there is ) software that will fix the single sheet feed problems on the Designjet Z3100-I would like to know how I can obtain this software.


I believe the sheet-feeding issues can be solved through a firmware upgrade. It has been about a year since I looked at this issue, and I know that HP moves resources on its web site from time to time- so the best thing to do is to go to the main HP Graphics portal, and search for z3100 and a combination of parameters such as sheet feeding, firmware update, and the like. You can also contact Jack directly through his web site at

 PS – depending on the size of the sheet – if the sheet edges are not ‘square’, you’ll have issues. It you can trim the sheet to 90 degrees on each angle, many of your issues will be addressed.


In the capture process, do you use a black surround to envelope the artwork and then direct the two lights at 45 degree angle from both sides into the inside of the surround toward the artwork? Do you use polarizing filters over the lights as well as on the lens? I have not used the surround yet but other photographers have said that I should. Maybe that’s why not all my colors are perfectly reproduced.


In capture, I usually use a dark neutral grey, or black surround. Color bounce is a big, big, headache. The angle of the lights depends on the reflectivity of the artwork. W/ the HP Artist software, one can light the artwork from one side only. I do not normally use polarizers; however, I do not hesitate to use additional lights and change the arrangement to use a shallower angle, lighting for fill and to kill reflections, etc. Hope this helps.

PS – remember to protect the lens using flags or other barriers – lighting that spills directly past the lens shade will help kill color and contrast.
