How to Deal with the Poor Fluency of Sublimation Ink on Inkjet Printer

remove the air bubbleNowadays, many inkjet printers use the Epson fifth-generation print heads. At the same time, piezoelectric inkjet printers also have many problems. If the fluency of inkjet printers after ink refilling is poor, short-term conditions may occur after printing for tens of centimeters. Today, I would like to share with you an analysis of the reasons and solutions for the poor fluency of sublimation ink.

Now the sublimation ink used in piezoelectric inkjet printers is water-based dye ink, which generates air bubbles during the ink refill process. Because the ink pump will draw the ink together with the air bubbles during the ink pumping process. You can start to do the head detection. When you see the ink out of the whole, you begin to
the air bubble in inkprint pictures. At this time, the bubbles in the ink are not completely discharged from the ink, there will be some very small bubbles in the ink because of the pressure. Air bubbles accumulate at the nozzle as the ink is ejected during printing. A large number of small bubbles form a large bubble, blocking the nozzle to form a gas plug. This causes a situation in which the ink will break after printing for a while during printing. This situation is likely to occur when just changed the ink or when install a new machine.

The solution: Fill the ink to the ink tank. Let the ink at the nozzle print out and leave the machine for 20-30 minutes before printing. So that the smallest bubbles in the ink can be removed to minimize the possibility of gas blocking.

1. Inspection method:
remove the air bubbleAfter injecting 25ml to 30ml of ink into the nozzle, suck the air in the pipe to install the sprinkler. Then place the sprinkler higher than the trolley for three secondsand put it upside down. There will be air bubbles rising inside the sprinkler. If the air bubble rise and stops slowly, it is normal. If it rises and does not stop, it can be judged to be the leakage of the installation.

2. Leakage phenomenon:
The bubble does not go inside the nozzle when spraying the picture; the bubble flows back; the nozzle holes accumulate ink seriously; the contact belt is stained with ink; the ink is broken when the picture is sprayed.

3. The solution:
The above phenomenon is that the mounting hole leaks. It may be too much force during installation. Then the installation hole of the nozzle is broken. We can use the middle hole of the bicycle inner tube to cover the nozzle mounting holethen lighten the ink needle.

Sublimation Heat Transfer Printing VS Direct Sublimation Printing: Know the Difference Now

The direct sublimation printing and sublimation heat transfer printing both are not the new terms for those who are working in the direct to garment printing and sublimation printing fields like sportswear printing, textile printing, advertising printing and other personalized printing stuff. But, which among these both is more useful? What is the difference between direct sublimation and heat transfer press technology? Let’s find it out here in this article.

What is direct sublimation printing?

Direct sublimation printing – Printing directly on pretreated fabricSublimation printing is direct printing on pretreated polyester fabric without using transfer paper. After direct printing, the polyester is heated for color production and fixation. Facility investment is required, but production costs are lower than those for sublimation heat transfer printing.

Here is an image below can help you understand direct sublimation printing process:

What is sublimation transfer printing?

Imprints a printed image of the transfer paper on the polyester fabric.

First, the image is printed on transfer paper. Second, the printed surface of the transfer paper is placed on the polyester fabric and the two are pressesd together at high temperature. The molecular chains of the fibers break on heating, and the sublimation ink molecules are caught between the fiber molecules and fixed on the fabric.

Here is an image below can help you understand sublimation transfer printing process:

If you’re not sure which process best fits your needs, we would love to explore these technologies further with you to match you with the right printer. Our textile print specialists can go through both processes to make sure that you have the right ways for your business.

The Causes and Solutions for Garbled Images in Inkjet Printers

inkjet printersGarbled images in inkjet printers occasionally occurs, this phenomenon confuses the
user. So we can not use the inkjet printer operations normally. There are many
factors that resulting in inkjet printers appear to map garbled. Just like data lines,
computers Drives, inkjet printer memory, and rasters and so on are all possible.We are introducing common troubleshootings and corresponding solutions to you.

  1. Data line failure

The data line is the only channel for transmitting computer print data to the inkjet printer. If the data line has a problem and the connection is not smooth, it will affect the transmitted data. And the graphics will be abnormal.

Solution: First check the data cable for dust, moisture, looseness, etc. Generally, pull out the data cable clean and then connected. If there is a disconnection, you must replace the new data cable.

  1. Inkjet printer memory problems

The probability of thermal foam inkjet printer (Piezo Inkjet Printer memory is integrated into the main board, so no problem) memory failure is still relatively inkjet printer memorysmall. Generally loose or wet will cause the memory to work abnormally. It will appear to be unable to print or even print garbled.

Solution: Pull out the memory card and clean it. Then use a fan to blow off the motherboard. Then reload the memory.

  1. Raster problems

Raster is one of the components that directly affect the print quality of inkjet printers. If dirt or damage occurs, it will cause print deviations, print failures, and garbled prints.

Solution: Clean the grating or replace it directly.

    1. The main board failurethe main board

The probability of failure of the main board is relatively low. But if it is determined
that there is no low-cost solution to the failure of the main board, it can only be called
after the sale. If the warranty period expires, it will be more troublesome because it will requires the user to pay for it.
