Lucy Can you be a bit more specific please? Do you have art work that you want to get printed and sell? If so I may know someone who can help :) Subject and size of image and length of run will all have an impact on who will be able to print them, not to mention paper quality, and the materials used in the original.
I was involved in a discussion about ltd. edn prints only last week & a number of pro photographers I know have actually come to realise that they are worth less than open editions! However I can appreciate the instant sellability of saying something is a "ltd edition". Is it a painting or a sketch etc? I will ask around for reputable repro company although you also need to consider its final value & amount of profit you will make. For example if you were thinking of retailing something at say £50 then theres no point in going to one of the top art companies that produce a giclee fine art print that costs over £100 to make in the 1st place! You need to get an idea of what price you want to sell it for before you choose your print method.
