Re: Artistico Unsized?

Or, should I definitely size it? I hate the idea of sizing paper, it's messy and slow (I don't have enough drying room for sizing in batches). Loris, for "drying room," either stack stretcher frames covered with screening and separated horizontally (by wood blocks, nails, whatever) that you can pile up to the ceiling (8 or 12 or however many you want), or line up parallel clotheslines, say or 4 front to back, separated by inches so you get room to clip on, say, 20 sheets in a very small space... in both cases you insure air circulation, hence drying. with a small electric fan to stir the air (no heating, just wind). Drying space is the least of the problems. J. I always try to use transparent / semi-transparent and non-staining / semi-staining colors. (Schmincke brand - it's the only artist quality watercolour paint I can find in tubes here in Istanbul.) I never got staining on unsized Masa paper - unless few cases where I used an overpigmented emulsion. Is it a good indicator that they won't stain with Artistico too? Yes, I know I should try and see for myself -> but I really want to have a nice gum print by the end of the week (I don't have Sunday for printing -> will be at Istanbul Park for the F1 race) and have little time. So, hearing some experiences would be good. BTW, I use digital negatives calibrated for 2A+1B traditional cyanotype (on Masa Paper) and they work fantastically. I decided to never, never try to calibrate for different colors, dichromate and pigment strengths with gum because: a) I don't have neither time nor patience to achieve this. b) More than one negative per image is too costly to me. (I had to switch to Pictorico since I use HP 9180 for making my negatives and I'm short of Pictorico. Plus, it's bloody expensive compared to Ultrafine.) Thanks in advance, Loris.
