Having used SNAP PAPER on several occasions, and never been disappointed, I can only add their first class service never seems to fail! We use A4 Matt 170gsm photo paper, a superb quality, smooth finish, bright white paper which works well with all types of inks and printers (ours HP and Canon) If anyone is unsure regarding SNAP's paper, ask for a sample pack, which is how we discovered there products, you will not be disappointed. Quality products at very reasonable prices when compared with top brand names such as HP or Canon own brand. SNAP PAPER delivers with speed and efficiency, on your door step before you know it!! We use it primarily to produce large images of engraved postage stamps, were clarity and sharp detail are important. MARTIN SNOWDON President, Redcar & Cleveland Photographic Society
