UV Printing VS Sublimation Transfer Printing

sublimation printingWhat is UV Printing?
UV printing is a unique method of digital printing utilizing ultraviolet (UV) light to dry or cure ink, adhesives, or coatings almost as soon as it’s hit the paper, or aluminum, foam board, or acrylic – in fact, as long as it fits in the printer, the technique can be used to print on almost anything.

What is Sublimation Transfer Printing?
Sublimation is the process of printing special sublimation ink onto special sublimation transfer paper using a sublimation printing technique. Instead of traditional inkjet transfers that print ink on top of the t-shirt or item, you’re working with, sublimation ink actually becomes a part of the substrate you’re printing on. How do you ask? It’s simple. Once the ink from your sublimation transfer paper is heat pressed onto the item you’re printing on, it opens up the pores of the fabric that you’re pressing heat onto. Once you press the paper onto your item and release pressure, the heat will cool and the ink will turn back into a solid form. The result? The pores will close permanently and encapsulate the ink within the polymer coating of your men’s t-shirt or women’s t-shirt. So the ink turns from a solid to a gas and them back into a solid—it’s like your very own chem experiment!

UV printingThe difference between uv printing and sublimation transfer printing is the following:

1. Different ink

Sublimation ink is dispersed heat transfer ink; UV printer uses UV ink.

2. The printing process is different

Sublimation Transfer Printing: sublimation print is to print the color pattern on the heat-resistant substrate first, usually using film material, and also need to go through the release process, and then combine the special transfer equipment to transfer the pattern to the hot stamping method. Product surface. Heat transfer printing needs to be equipped with matching products such as heat press machine, baking tray machine, cup making machine, etc. Different products need to be processed accordingly.

The UV printer directly prints the desired pattern directly on the surface of the product, which is essentially a type of piezoelectric inkjet printing device. The ultraviolet wave emitted by the LED cold light source lamp reacts with the photosensitive curing agent in the uv ink, causing the pigment molecules in the uv ink to solidify on the surface of the material.

3. The application industry differences:

Sublimation transfer printing is currently used in clothing, plastics, toys, electrical appliances, gifts, advertising banners and other industries. The advantage is that it can be printed on curved and irregular surfaces.

UV printers are mainly used in many industries such as mobile phone shells, ceramic tiles, glass, metal, building materials, advertising, leather and so on.

The advantage lies in that it is desirable to wait, the operation is convenient, and it can achieve instant production and mass production.

How To Solve The UV Printer Failure In Winter?

How To Solve The UV Printer Failure In Winter?

UV printing

When it gets cold in winter every year, the number of failures of UV printers will also increase, mainly in four areas: print head nozzle blockage and disconnection, consumables solidification and condensation, electrostatic interference, and voltage instability. In view of these situations, how to prevent them in advance.

1. Print head nozzle blockage and disconnection. After the temperature drops in winter, the print head will be “clogged or disconnected”. Don’t worry too much. This is mostly because the viscosity of the UV ink increases and the fluency of the ink decreases after the temperature drops. Individual nozzles do not emit ink smoothly.

Solution: In addition to the automatic stirring and heating of conventional large ink cartridges and secondary ink cartridges, heating plates can be installed on both sides of the ink outlet of the nozzle. If it is not convenient to install, you can choose a small sun and keep 30cm Distance, illuminate the head car, if possible, you can turn on the heating or air conditioning to keep the working environment temperature of the UV printer above 25 degrees.

2. Consumables solidification and condensation. Users of UV printers found that the ink in the UV ink bottle has become viscous, and some of it has condensed. When this happens, it means that the ink has been scrapped and cannot be used, mostly because the ink bottle is placed directly on the ground.

Solution: The storage of consumables in winter must be placed on the shelf, not on the ground, and not in the open air.

uv printing3. Electrostatic interference. The wetlands where static electricity interferes with the winter air are reduced, and when the dust increases, static electricity often occurs. The direct effect is that the ejected ink droplets deviate from the direction due to static electricity, causing the phenomenon of “flying ink” or “ink splashing”, and the print quality will be seriously reduced. In severe cases, it will cause the circuit to burn down.

Solution: In addition to installing the necessary ground wire, the cleaning of the working environment of the UV printer requires 2 days/time for maintenance to reduce dust. If the air is dry, just turn on the humidifier. If possible, an electrostatic rod can be installed on the machine to eliminate the electrostatic interference of the material itself.

4. Voltage instability. In winter, due to the heating demand, a large number of electrical appliances will be turned on, and the current and voltage will be overloaded. These instabilities will affect the normal operation of the UV printer in the light of it, and will directly burn the internal circuit.

Solution: In addition to choosing a UV inkjet printer from a regular manufacturer (the circuit system has preventive and emergency solutions), a voltage stabilizer must be installed, a backup power supply and a separate line for the equipment must be installed. It cannot be mixed with other electrical appliances.

What Is The Accuracy Rate Of Sublimation Paper Print Color?

What Is The Accuracy Rate Of Sublimation Paper Print Color?

 

dye sub paper

Are you wonder whether our paper can print out colours as artwork exactly?
The answer is “Close, the transfer rate can be over 95%, but not very likely to be exact.”

There are too many factors involved, such as media type, colour range/settings, shifting.

Media type – If your artwork was created on paper/canvas and was later photographed or scanned for digital printing, the camera/scanner/monitor/lighting output is already affecting your artwork. Same goes for artwork created on computers; What you see on a digital screen is hard to reproduce exactly on a different medium. Furthermore, printing on paper and printing on fabric results in different outputs because of surface, material, and printing variations.

heat transfer printingColour range/settings – Inks and printers have a range of colours they can output, which is also known as the colour gamut. Like how there are some colours that are out of the colour gamut on your monitor, there are some out of the printers’ range as well. Therefore, colours out of gamut on the printer will be printed to the closest colour it can produce.

Shifting – When the fabric shifts, the print will look like it has a slight shadow, more evident on areas with darker colours. We try our best to prevent it, but it is a natural printing variation. To ensure that the colours print as close as possible, please make sure your file’s colour profile is in CMYK for CMYK printing and have a sample printed first. We also recommend printing a colour chart so you can easily use it as a guide to predict final approximate colour output on a particular fabric.
