Started work on the Gassing Off Cabinet Again
Had a bit of time this week (little quiet!) and so after catching up on things that have been hanging around I started printing a wrap for next week. Then the long standing issue with larger prints appeared again.
Currently my gassing off process is stand the roll on a milk crate in a loose state and go find something else to do. I have tried rolling out but get contaminants and I do not believe this is all that effective or accurate. Just guess over night will do?
Last year I started plans for a Gassing Off Cabinet to try to better the situation and got too busy to start it so now is the perfect time….
The cabinet is planed to be angle with dibond sides will either seal or use VHB tape to make air tight if warranted. I have four huge computer server fans mounted in an aluminium panel that I plan to repurpose at the bottom of the cabinet to suck out the air.
The fans are 48v dc 880ma units. These are modern type fans that have 4 wires + /- then a speed control and a tacho. I decided not to bother with the speed element and so disregarding the speed control and tacho the fan will auto run at max rpm. If i notice it hovering then linking the speed control to the earth will change the fans to run at low speed. (Any techies with knowledge on power please feel free to correct me if wrong and transformer info/ advice would be great as needed).
So based on my plan the Ecosolvent ink will print onto media of choice collected on the take-up whilst two 12" fans blow air over it to aid drying. Then into the cabinet with the fans sucking the air from the bottom (as solvent gathers at the bottom not the top – Thanks to UK Signboards member pointing out). I can’t work out airflow until the fans get power but I am hoping this will increase Gassing Off tremendously and no contaminants.
Any comments, ideas to make better or experience would be an interesting read…
