having used a multitude of different cotton papers and enjoying the experience , although a expensive one. i decided to buy a large sheet of 300gsm cartridge paper, very white , flat surface and cheap 1 pound. wasn't expecting a great showing from this paper, swelling maybe,blotches possibly, strange coating behavior or maybe unusual coloration. what the hell ill give it a go. i applied two generous coatings of gelatin 4% coated with a high quality brush, temp of gel was 60 c approx, so quite hot. allowed to dry off naturally and finished with hair dryer. sensitized using a soft brush, first coat allowed to dry then a 10 sec blast from hair dryer, second coat of sensitizer , followed by a 1m 30 hair dryer on each side. made test strips in same manor 45 second hair dryer on each side i added a -10% exposure compensation to the print time due to moisture level compared to test strip.(moisture speeds up exposure, and as the test strip is likely to be dryer than larger sheet , well you get my point, 10% was perfect) all i can say is wow, beautiful, smooth coating, nice neutral brown tone, great contrast. and the most important thing a ice white finish to the paper. why am i writing all this, well because if you haven't slummed it in the cartridge paper world then do so , you wont regret it.
