Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
i would think the humidity would be the factor because:if you look in the picture, we have the i-Image in a room that has two vinyl curtains that i drop down over the weekend. the two humidifiers keep the i-Image at around 35-45% humidity. trying to humidify the entire room (that has the screens and washout tank) would be nearly futile.the ink we use is type K and we havent added any since march - we have averaged 20 screens a day.
when we bought the i-Image in 2014 it came with Type K. never had an issue with the ink. we had the two printheads replaced last year and stayed with the Type K.

It’s your opinion or preference. Wax has the benefit of working in all environments because it lands in a more solid state on the screen, and is a wax and not subject to water or cold. It’s subject to more heat, but in extreme cases that would not affect screen printing and making screens. To say “go wax” is to indicate that wet ink does not work at all, easily, or well...and that would not be correct in the least.The answer is/can be, multiple things.1, The screen has sat too long. T-6 seems to like fresh screens and a little tack to them. Typically, most everyone uses screens within same day to 3-5 days. The older the screen, the more chances are given for pre-exposure and humidity changes. Not good for wax or wet ink.2, The recent changes in weather and humidity does affect the bonding with some screen rooms and no change in other screen rooms. It’s a minor/easy fix balancing act for some.3, The technique of coating can exaggerate this effect of change in humidity. Those who coat 1:1 on all or (low mesh), stand more of a chance of not having a flat surface to work with and the ink may pull or puddle down into the valleys of the mesh thread texture or (in the waffle valley). This is not a great method and would not be considered the industry standard but many people do this for ease. Especially on lower mesh. Leaves channels in the gasket for ink to get pushed out of the sides causing blurred edges and ink bleeding.M&R does sell various types of ink, but they don’t intentionally sell those for various shops and environments to offer a variety. That is not their goal. The reason they have several, is to continue to make one best one, or to improve an issues with the previous “new” best one. Since there are shops that have never had any issues at all, there are some that still want their older "original”one and don’t want to chance changing it up. Damp rag is another quick fix.
Wax

I have used both. Wax is the only way to go!! I will never go back.

Damp rag is another quick fix.It’s for people in the future who are on the fence. Buy wax. It works over and over and I don’t see any posts or articles suggesting wax has ever had an issue “sticking” to an emulsion. The OPs post is proof they ink had issues, and might still have issues under certain environments. So if you’re on the fence do you pick a solution that has had problems and might still have problems under certain scenarios or do you pick a solution such as a douthitt machine that has proven itself over and over just works regardless of the environment. There is only one wax. Douthitt or spyder or Kiwo only sell one wax. That’s because it works in every environment on every emulsion. The simple fact m&r sells different ink (I didn’t know this) is reason enough to not buy that solution. Does a consumer really want to think about what ink he might have to use during certain times of year or with certain emulsions. Or does he really want to worry that if he moves his shop that his new location might have different variables that might or might not require different ink. Just cut the variables out and buy a wax machine.So for people reading this in the future which soliton do you want to trust your mortgage with?
