Yes, humidity is important. Get a small digital humidity guage and put it next to your printer. You also need to think about what the temperature / humidity is at night. Too low of humidity will cause your print head to dry out.

Proper humidity level (at least 40% to 50%) is a major factor in your printer running well. You may face some issues in a open space like this, especially during the cold months. Heating will dry out the air. leading to humidity levels as low as 5 to 10%. Placing a humidifier near your printer can help. As Mark pointed out, the first thing to do is to get a humidity gauge (available for as little as $10). It is the only way of really knowing what your actual humidity is.

I'll add my vote for proper humidity. It makes a HUGE difference in print quality and print head life. You are going to have challenges keeping high print quality if the humidity drops much below 50%.

We keep our print shop at 21C (70F) and 60% humidity 24 hrs/day. You can't do that in a shopping mall, so you might consider getting a humidifier that exhausts its air out the top (Sears has one) and park it directly under the printer so that the humid air blows up inside.

We also found that if the air temperature goes much above 26C (78F) print quality drops dramatically and the print head starts to clog, even at 60% humidity.

Here is a clever idea that a customer used with their Veloci-Jet XL printer. They bought a greenhouse (available at Harbor Freight) and put their printer and humidifier inside to control their humidity level.

not only would that help with humidity but would protect against pretreatment misting

 

That brings up an interesting question ... how do you keep pretreatment spray mist from floating all around the shopping mall? The stuff is not toxic, but it can be a bit annoying and it leaves a sticky coating on everything it settles on.

If you pretreat inside the greenhouse enclosure, how do you keep the pretreatment mist from getting inside the printer? That can cause real problems if allowed to get on the print head.

Just curious.

ok, so can i do this...

get a tarp from home depot, cover the t-jet, buy a humidifier and place it under the tarp so the humidity can stay with the t-jet, and leave it like this during the nite and the day while i dont use the t-jet?!

i just asked if i am able to build another little room for my t-jet and they said no cause if the building codes and what not.

 

WOAH Harry!!! HAHAHA If i had the space to do that i will most deff do it! Im going to see what i can do!

 

The nice thing is that the greenhouse comes as a kit so it can be assembled pretty much anywhere.

Please note. The greenhouse is for helping keep the printer in the proper humidity level. NOT for spraying pretreatment in. If you are spraying pretreatment by hand then it has to be in a separate area away from the printer, preferably in a separate room.

Yes the little room i use is 3 by 4ft. and i have a roof over it and i use heavy and long curtain as a door and its worked really goo, but can i do this...

So if i do decide to use the green house will it clear the problems im having while printing?! Cause white ink does come out but it comes out dull
