Humidity at 50% or greater, what happens when its below 50% humidit and how do you humidify?

DTG BEST PRACTICES BY MIND’S EYE
As we are in a more northern climate we run into humidity issues once the heat goes on. It is critical to invest in a hygrometer (unit that checks humidity) and keep it by your DTG (preferably one at each printer). Our printing area is roughly 2000 square feet, 28000 cubic feet when you consider the ceiling height.
We tried using a couple of small localized humidifiers and found that we couldn’t keep our humidity above 50%. As you know, low humidity dries out the ink of the face of the printhead and capping station, leading to more maintenance and potentially shortens the lifespan of the consumable printing components. We looked into a humidifier for our HVAC system but it was going to be several thousand dollars. Instead we invested in 4 mid-size humidiers from Lowes that ran about $80-90 each and we run them continously in the DTG area, they keep the levels above 50%. We look at them as consumables as we would have had to spend 10-15 times as much to add this feature to our HVAC system.
Pre-Heat Pressing shirts before Pre-Treating
- Matt Down Fibers – we pre-press all shirts (light or dark) for 5 seconds at 340′ F to dry the shirt and to lay down the fibers, the light shirts go straight on to the printer the darks are then pre-treated, wiped down with a foam brush and then pressed again for about 30 seconds to dry the pre-treat
- Less time to cure pre-treat – we press our pre-treated shirts for about 30 seconds, basically until they are dry
- Makes prints look less fuzzy ? – without a doubt, pre-pressing of shirts prior to pre-treating helps to lay down ther fibers – especially on more lofty stle garments
Go over some of your multi tasking thoughts and procedures – full production on the two Vipers we have is basically a 1 1/2 person job. I think that shop layout helps to increase the efficiency of the operation. (see Greg’s shop layout that he emailed). There is more time for multi=tasking on dark garments than on lights. The throughput on lights is great enough on two machines to basically call for all hands on deck.
Other practices that give you good prints with less waist or less wasted time etc. – take the time to do a test print or two on an old garment to verify the colors, size and positioning of all elements of the graphics. Also, do a nozzle check before starting production, make sure you have plenty of ink in your printer and all your presses are on an
d to temperature before starting production.
Lastly, the Laser Allignment, give me a short description on how you made it, where to get the parts and about how much money it cost to make it. – Basic screenprinter trick. Print the image to be targetted onto an old shirt in the position you think is right. Move the entire shirtboard system over to your laser alignment station and target the areas that were printed with the lasers. Now you use the station as a targeted loading station, taking the “guess work” out of position printing. The whole system can be built for less than $300.
