How to Troubleshoot Digital Printing

When repairing a bothersome print that is done on an electronic direct-to-garment printer, experience is, without a doubt, one of the most important tool in your toolbox. I have actually additionally located my display printing experience to be of worth.

After display printing for 25 years, I can troubleshoot a display printed layout in seconds. Now, I have actually transformed that experience into electronic printing. Repairing will be harder if you have no experience or criteria from previous history.

In the beginning, my store developed a treatment to follow whenever we knew something wasn't right, yet we didn't have a hint what was wrong. This procedure includes first inspecting the substratum, after that the nozzles, then whether we made any kind of changes in the parameters as well as, lastly, the art work.

SUBSTRATES &amp; PRETREATMENT

One of the first things you must keep in mind is that you need to watch out for the print jobs you approve and the substrate on which you intend to publish. If you wish to save time, and also protect against headaches as well as disappointment, come to be accustomed to brands that print well for you and stay with those brands. In our store, we will not electronically print anything except 100% cotton Tees, and also we are very solid regarding that. You can shut down your store attempting to publish substratums never ever planned for electronic printing. We advise particular brand names and also we discourage certain blends, like 50% cotton/50% polyester.

If we get customers who definitely urge we publish on 50/50 blends due to the fact that it's the only choice readily available in a specific color, we need them to authorize a paper ahead of time that states the threats involved, and that this t shirt is not the best option. We ensure that customers realize ahead of time that the outcomes may not be what they are anticipating.

T-shirt brand names additionally significantly affect pretreatment, as well as the proper amount will certainly differ depending upon the brand and its country of origin. In some instances, you may need to trying out a t-shirt to see what works ideal. In many cases, we invested our very own time and money into doing test prints to make sure a customer would enjoy.

One of the most important element of pretreatment application is consistency, which is difficult to attain when using a spray gun. If the exact same person is doing it every single time, he might establish an instinctive sense of how much pretreatment will suffice. Still, it is, at best, an educated guess. If you have multiple people pretreating garments, each person will certainly more than likely do it in a different way and also with differing amounts.

Because of this, an automated pretreatment machine is a worthwhile financial investment. It allows you to use a regular layer of chemical. Commercial equipment has the pretreatment procedure currently integrated in so that it's not an issue.

When pretreatment is refrained from doing effectively, the most obvious indication will be irregular shade. Poor pretreatment triggers bad opacity, which results in bad shade. That's very easy to fix due to the fact that it's so noticeable. It ends up being a lot more noticeable when you wash the t-shirt since the inks will come out.

Another repairing issue related to pretreatment is the hand or feel of the garment. An irregular pretreatment layer can result not just in washed-out sections of the design, but it likewise can result in a rough or uneven hand.

Badly carried out pretreatment additionally can result in fibrillation. There has to be enough pretreatment applied to ensure that the substrate's fibers are sealed down. This applies whether the t shirt is being treated in a warm press or a conveyor clothes dryer. I would certainly estimate that 90% of the moment, the wet tee shirt looks great, but the real outcomes are apparent after the tee shirt has been cured.

NOZZLE &amp; SETTINGS CHECKS

Once you've gotten rid of the t-shirt or pretreatment as possible root causes of an issue, the next action will certainly be to check the nozzles. Many equipment has a diagnostic function that permits you to do this. You ought to make sure that all nozzles are shooting. We regularly run nozzle tests before the day starts.

Nozzle checks are a lot more crucial if undesirable problems, such as reduced moisture or high warmth, exist in your shop. On nowadays, we immediately run nozzle examinations if we believe any type of problems.

If a nozzle check shows any type of problems, the next action is to run numerous purge cycles on the equipment. If you find a clogged up nozzle, it must be cleansed. Often a cleanup will clean it out. Other times, you may need to purge the print heads, which can take hrs.

Commonly, you will certainly experience the most awful problems with the white print heads due to the fact that the titanium dioxide in white ink has a hefty settling price. This pigment resolves rapidly due to its weight as well as has a tendency to conveniently clog heads as well as lines. Continuously monitor your nozzles so you are always aware of their condition. Some equipments have settings that will certainly allow you to make up for clogged up nozzles by bypassing the non-firing ones.

The bright side is that, most of the times, nozzles obtain blocked at a steady rate. This means there are some indication that allow you to act prior to the problem gets out of hand. Among the very first indications of a clogged nozzle is streaks in the print, and also it becomes a lot more evident as the clogging boosts.

The third location to check for printing issues-- if you are handling a repeat order-- is transformed setups. This is where great paperwork enters into play. You need to track all the criteria for every job you do. At my shop, all requirements for a work are become part of a standard work order by the machine operator. That order is gone on data. This makes it very easy to double check that we are utilizing the same setups as in the past for the exact same work.

It's not uncommon to work that was printed, the consumer enjoyed, and also he comes back for even more. You publish the work once more, but this moment it does not look rather ideal. This is why it's important to have actually written records of precisely just how you formerly printed the task and also its connected expectations.

check this link that need to be recorded consist of just how the ink saturation down payments were modified, the printing setting (top quality or poor quality), how the white ink was laid down and how the pretreatment was applied.

ART WORK

The last area to examine is artwork. Individuals tend to create art in a low-grade application, such as a Microsoft Word documents, a publisher file, or they supply you with a low-resolution jpeg. As a store proprietor, you need to make a decision whether you will provide services to take care of poor art. If you have a plan to publish just art created in-house, you address a great deal of problems created by poor artwork, but you are getting rid of 90% of your service.

When we get artwork from customers, we constantly do a preflight check (evidence) in Adobe Photoshop before we start the work. A person that comprehends resolutions as well as the tearing software made use of to refine print work need to do this. Everything needs to be looked for mistakes. If errors exist in the pixel data or the file is corrupt, this may not be visible to the naked eye and also will trigger problems when the file is being ripped. Recognizing just how to resolve these problems is a product of experience. This is why I emphasize the importance of recognizing graphics software program.

Various other concerns that can emerge in art work may entail tiny type or trying to strike a specific shade. In some cases, you can obtain jagged edges or inadequate enrollment as a result of bad pixel data. When printing on darks, the underbase usually will hang outside of the CMYK. You must have an extensive expertise of your graphics software application to be able to take care of such problems.

These locations touch on the most typical fixing problems you will certainly run into. Every store as well as equipment is different, and also every digital decorator is bound to run into some special problems. If you use this four-step treatment, it can help you narrow down the reason for your problems so you can identify a service quicker. And, if you are diligent regarding recording the problem as well as its options, you will certainly soon discover that time spent in troubleshooting is minimized, as well as you can continually output the print quality that your customers will certainly anticipate.
