A little more information would be helpful.
What size would your graphic work be?
Is this graphic work prior to digital artwork?

apologies this is printed work ranging from posters to leaflets, stationary and books, so both large and small

I bought a few lights, shot on white formica, and had pretty good results. You can also use white posterboard or foamboard to use as reflectors. You may be able to get away with reflectors if there’s enough natural light, but a few lights will make a big difference. Example below.

On the cheap lighting solutions are much more available now that CFLs are becoming common. Look for Daylight rated bulbs like the GE Energy Smart CFL bulbs.

You can get a few of these, and some (2-3)utility spot lights (clamp style).

If you have a tripod, set up a blank location on a wall in a darkened room with a piece of Black or White mat board. Attach your work to the mat board and then set up your tripod about 3-6 feet away. using 2-3 spotlights with your daylight CFLs, aim them so that they’re roughly 30-60 degrees to the artwork and on each side (this will eliminate any glare or shine).

Do a search on Google for Copy Photography. I’m sure there’s other useful tips, like manual settings.

If you live near a college/university, especially a liberal arts college, there’s always slide photographers available, you might even be able to talk your way into the lab t
