FAQ of heat transfer printing

what is heat transfer printing

heat transfer printing is a new method for printing patterned goods. It is suitable for a small number of personalized goods and the printing of full-color images or photos. At present, it has become increasingly popular. The principle is to print the digital image on the special transfer paper through inkjet printing or laser printer, then put the special transfer paper with the pattern on the commodity, and use the high-temperature and high-pressure transfer machine to accurately transfer the pattern to the surface of the commodity, and then complete the commodity transfer

not all goods can be printed with heat transfer printing, which involves factors such as heat resistance, smoothness. Due to the continuous progress of technology, the products that have been developed by using heat transfer technology include: clothes, cloth bags, hats, pillows, mugs, porcelain plates, ceramic tiles, watch cases, mouse pads, coasters, hanging calendars, medals, flags, work medals, doorplates Wait for hundreds of goods. We will use the latest heat transfer printing and other technologies to continuously develop more personalized goods, from head to toe, from wear to use, to meet your desire for personalized performance. Heat transfer technology can also be divided into several types, the most important of which are film transfer and sublimation transfer

common textile transfer printing drives the moving beam to move up and down to realize the loading of samples (tightening and bending attachments are installed between the moving beam and the workbench, which can carry out tightening and bending experiments on metal or non-metallic material samples; tension attachments are installed between the moving beam and the upper beam, which can carry out tensile experiments on metal or non-metallic material samples) Technology common textile transfer technology is film transfer and sublimation transfer

1. Sublimation transfer: at present, the technology is mainly applicable to clothes with polyester on the surface, such as fast sweat wicking shirts and physical comfortable shirts, and white clothes are the best (the printed pattern is white, but other parts of the clothes can be other colors, such as color sleeves). After colored clothes adopt digital sublimation, ink and colored fiber will fuse, which will make the color of the pattern different from the original, so it is not recommended to use

2. Plastic film transfer: at present, the technology is mainly used for clothes with extremely high cotton content. All colors can be transferred with adhesive film, but the expensive "special transfer paper for dark clothes" should be used for dark clothes, which has heavy gum and unstable quality

the weight of ceramic and gold car bodies has been greatly reduced by 230kg; Secondly, the transfer technology of products

ceramic products adopt thermal sublimation transfer, which sublimates the ink onto the products at a high temperature of about 200 degrees Celsius, with sharp colors and high reliability of the patterns. However, general mugs cannot be directly transferred, and the pattern can only be transferred after a special treatment of coating

heat transfer method using an electric iron due to the limitation of the calorific value of the electric iron, generally A4 size (20) cannot be transferred × For items above 30cm), the electric iron must be adjustable, and the higher the power, the better

1. First adjust the iron to the cotton fabric gear (i.e. about ° C), and preheat until the insulation indicator light is on

2. Put the clothes flat on the ironing board and iron the part to be printed for a few seconds to remove the moisture

3. Place the transfer paper with the printing side down flat on the part of the clothes to be transferred, and stick the four corners of the paper with adhesive to prevent the paper from moving

4. Lay the high temperature resistant flexible asbestos cloth on the clothes pasted with transfer paper, flatten it, and clamp it on the edge of the ironing board with four clips

5. Use an iron to press slowly back and forth on the part of the heat-resistant cloth with transfer paper for seconds, and the time can be flexibly controlled according to the size of the pattern

6. Remove the transfer paper from the clothes before it cools, otherwise it will stick

maintenance methods of T-shirts and cotton fabrics after transfer printing

1. The T-shirt just transferred will feel a little hard, and you will become softer after washing

2. The newly processed T-shirts can only be washed after 2 hours. Turn the clothes over to wash

3. Do not rub the surface of the T-shirt pattern with your hands (the surface material of the pattern will not adhere to dirt)

4. Do not wash with detergent containing bleach

5. Wash with warm or cold water below 40 ° C

6. Try not to use the washing machine

7. After washing, do not use the dryer to dry

8. Dry it naturally, don't twist the clothes, and don't expose the T-shirt to the sun

9. If clothes need to be ironed, medium temperature steam ironing can be used after drying (high temperature ironing is not allowed for those containing elastic fibers, so as not to damage the organizational structure of elastic fibers and affect the elastic effect of clothes). Do not iron directly on the pattern

10. After ironing, don't stuff the clothes into a narrow space. You can hang them on a hanger or spread them flat to maintain the flat shape of the clothes

use of heat sublimation ink combined with modifier to transfer textiles

transfer with heat transfer ink. Print the pattern on ordinary inkjet paper or special paper for heat sublimation. Be sure to spray some modifier on the place where transfer is needed, then heat the tablet machine by 180 degrees, and dry the clothes on the tablet machine before transfer. In order to avoid yellowing of cotton cloth, the solution is to pad a layer of isolation paper around the clothes during transfer printing. Modifier is only used in thermal sublimation transfer printing.

some textile fabrics containing chemical fibers can be directly used with thermal sublimation ink without modifying the modifier after testing.

generally speaking, the temperature can enter thermal transfer printing between ° C. the baking time and the area of baking printing pattern, as well as the difference of coating, ink, transfer paper, ambient temperature and humidity used have an impact. There is no absolute formula to check. The higher the temperature, the shorter the time required, The time range is within seconds. It should be noted that the baking time with transfer paper and ordinary ink should not exceed 40 seconds

how to use heat transfer coating

it can be directly sprayed, soaked or poured on the surface of the work. When the coating on the surface of the work is drained and no longer flowing, it can be baked in an oven that has been heated to 220 ° C for 10 minutes at 130 ° C for about half an hour. If it is found to be yellowing, it is too long or the temperature is too high. If the paper is stuck during transfer, the baking time is too short. It is suitable for friends who use a lot

the amount of 1 liter of coating can be sprayed with 5 square meters of work, or about 300 mugs

scope of use: flat materials such as wood, metal, stone, etc., can withstand high temperature to 220 degrees, and can be used for more than 10 minutes

1. First wipe the surface of the medium with the washing supplies in the detergent

2. Turn on the oven or drying oven while wiping the medium, and let it begin to heat up

3. Put the wiped media into the container with coating and soak it. After coating the surface evenly, take it out and put it on the shelf to dry. When there is no coating flowing down, put it into an oven heated to 220 degrees for baking. The time is set to 10 minutes. When it is time to take it out, you can use

precautions

1. When baking metal plates, be sure to dry them first and then put them into the oven for baking, otherwise they will blister

2. The coatings produced by some companies need to be mixed by two solvents in a certain proportion, that is, two-component coating

3. Baking free coatings do not need to be put into the oven, It can be dried at room temperature

what is the advantage of Teflon heat transfer coating? Teflon, also known as Teflon, Teflon, chemical name: polytetrafluoroethylene (PTEE), referred to as F4, Teflon has low friction and wear resistance; Humidity resistance; High insulation

in view of the excellent chemical properties of Teflon, our company has successfully applied it to the heat transfer industry through repeated experiments, and developed a one component low-temperature baking Teflon heat transfer coating, which can be cured into a film at 80C, 30 minutes, 130c, 20 minutes, 200C, minutes. The film performance test is as follows:

gloss (60 ℃

pencil hardness

adhesion (1mm cross cut) 100/100

no crack and falling off

solvent resistance (100 times of controlled washing with methyl alcohol)

acid resistance 10%hc 115 minutes

salt fog resistance 2000 hours

artificial aging resistance 5000 hours

can ordinary ink cartridge heat transfer paper bake ceramic cups and plates

some friends want to own DIY image mugs, but they don't want to. 2. The experimental standard refers to ISO, ASTM, DIN, GB, BS, JIS, etc. paying a high price to buy a set of heat transfer ink cartridges for the printer, and taking out the ink cartridges before they are used up and replacing them with ordinary ink cartridges not only causes waste, It will also harm the printer. In fact, heating the transfer paper with ordinary ink can also transfer the image to the coating Cup. It should be noted that: try to cut off the excess part of the pattern, because the heat transfer paper has a layer of plastic film, and the ink printing place can't be seen on the cup, but the part without the pattern will transfer some plastic film that is generally difficult to design to the cup, which will affect the overall beauty. In addition, it is best to apply a layer of varnish after printing, so that the cup will appear very bright and clean. Of course, if the quantity is large, sublimation ink is still a little more expensive than transfer paper, and the waste rate of transferring mugs with transfer paper and ordinary ink is higher. Whether/span uses heat transfer paper, water transfer or embossing to realize the image transfer of porcelain, although it does not need coating, it is equivalent to sticking a layer of film on the surface of the cup. Unlike heat transfer, the image completely penetrates into the coating of the cup wall, and there is no bump

how to use the thermochromic coating

at present, the thermochromic coating that our company is developing includes the following types: black, red, yellow, blue, You can also develop derivative colors of these colors, mainly for mugs. When hot water is poured in, the color will gradually fade out and reveal the transfer pattern. It will be restored to its original state after cooling. The traditional color changing cup is coated with a color changing coating before transferring the pattern. The disadvantage is that you can see the trace of the transfer ink when you look closely, because the color changing coating is below; Our products are printed with patterns first, and then coated. When heated, the coating color gradually fades, and the image slowly displays. After cooling, there is no image at all, which really gives people a magical feeling

can standard baking coasters bake small caliber cups?

baking coasters generally have two kinds: Standard coasters and small caliber baking coasters. The standard pad is usually called type I baking coaster, which can bake 7 Cm porcelain cup; Small caliber coasters, i.e. type II baking coasters, can be baked and printed 5cm caliber Cup here we provide a simple and effective way to make the standard baking coasters can also bake and print 189 bone china cups and other small caliber porcelain cups, which not only reduces the capital investment in your equipment, but also reduces the trouble of replacing coasters.
