hi. i have a few questions about my new epson 1100. first, i want to have it all black, but if i install the color cartridges first and run them through, can i then switch them to black? or do you have to run all black from the get go? second, my main thing i'm going to be printing is transparences for screen printing. i've seen conflicting opinions on the matter, but which ink should i use for that? i have waterproof transpacences i'll be printing on. i can get the refill ink and refill the oem cartridges, correct?
