If that seems confusing, come to Louisiana, where we use "arpent" as a measure of both distances across land and area of land. *The use of "point" for type sizes refers to 1/72 inch. Two papers with the same lb or gsm specification can have significantly different thicknesses. These are not measures of thickness, they are measures of the weight of a specified amount of it. You will also see paper specified by "lb" / "pounds" or "grams per square meter" / "gsm". Paper thickness is stated in millimeters (mm), or in the English system, both "mil" / "mils" and apparently in this context "point" / "points" / "pt"* mean 1/1000 of an inch.ġ inch roughly equals 25.4mm.** So e.g.
It's not really complicated once you learn the terminology.
I'm just so confused when it comes to thickness of paper, etc. Unfortunately it's somewhat thinner at 16.5 mils. if you want to print one sheet for the front and back covers of letter-size volume, you want 11x17" paper so maybe Hahnemühle Photo Rag Satin ( ).Īnother paper I really like, that has a satin-type finish and is reasonably thick, is Red River Palo Duro Softgloss Rag. Looking at B&H, there are a fair number of inkjet photo papers with a thickness of 22 ± 3 mils (i.e., 19 to 25 mils-a semi-arbitrary 'close enough' I chose). Unfortunately, most of the papers in this thickness range will have a matte surface, not a luster / satin one, but a few will. So then you need a thicker inkjet photo paper. I'd like to print directly to some sort of luster finished paper and do away with the middle man (photo paper). Obviously thickness is not the only issue stiffness / flexibility and weight (area density) also relate to this. That is pretty thick, and it would not surprise me if some materials of that thickness don't feed well in the ET-8550, so that's one potential limitation. If I understand this correctly, what you mean by "22pt coverstock" is paper that is 22/1000 of an inch thick and in this context AFAIK that is more usually called 22 mils, and equals 0.56 mm. So it sounds like what you want is a comparable 'paper' / cardstock that is suitable for printing with your ET-8550. Good inkjet prints require the 'paper' to have a special ink-receptive coating. I suspect the reason that prints directly on the coverstock look bad is that it is not intended to be printed on with an inkjet (it's intended to be printed on with a laser printer or not at all). I have to print on the adhesive photo paper and adhere it to the coverstock. Question: Is there a way to print directly on 22pt coverstock without the ink from the ET8550 bleeding? The prints look bad and dull. I do hope this is the right location/forum.Įquipment: Epson ET8550, LD Adhesive Photo paper, 22pt coverstock
