Xinxiang Custom Ceramic Mug Manufacturer, Ceramic printing mug, is a paste method to move the colourful pattern on the flower paper to the ceramic mug body. Ceramic decal paper production process for printing porcelain ink, porcelain ink is rolled from ceramic pigments plus oil. Printed with ceramic ink into a flower paper pasted on the ceramic mug, it must be 700-1300 ℃ firing, in order to present a variety of bright colours on the surface of the ceramic cup.
Ceramic printing process is generally: first of all, according to the design, colour separation. According to the characteristics of ceramic pigment overlay colour does not change colour, red, blue, green to be separated. At present, most ceramic factories are selected large film flower paper, high quality requirements for printing, the choice of small film flower paper. The quality of the large film flower paper is not as good as the small film flower paper, however, the large film flower paper than the small film flower paper price is low. For more detailed information on ceramic flower paper categories and decal techniques, see: Decal paper categories and decal techniques for ceramic coffee mugs.

Ceramic decal process operation mainly includes the following steps:

1. Preparation

Design pattern: according to the shape, size and use of ceramic products, design a suitable applique pattern. Patterns should be creative and in line with aesthetic needs.
Production of printing plates: the designed pattern through the plate-making technology, to produce a plate that can be used for printing.
Prepare ceramic blanks: Ensure that the surface of ceramic blanks is clean, flat and free of impurities such as oil and dust. According to the need to trim and polish the blank.

2. Decal paper production

Selection of paper: the choice of paper suitable for ceramic appliqué, the paper is required to have a certain thickness, toughness and ink absorption.
Printing patterns: the production of a good printing plate installed in the printing machine, the pattern printed on the paper. The printing process should control the amount and uniformity of ink to ensure that the pattern is clear and colourful.
Hand-painted plate:
Hand-painted plate is more technical, is all by hand technology to depict the screen on each colour palette, with points and lines of the two ways to draw a combination of colour plates. The handmade version of the dot is more suitable for printing ceramic decal paper, because the handmade version of the dot is thicker than the mesh version, due to the ceramic pigment is inorganic pigment, hardness, coarse particles, not easy to crush very fine, so the handmade version of the dot is thicker in the printing process of the ink absorption is more sufficient, so that the pattern of the outline of the part of the display is clear. But the shortcomings are depicting a flower bottom plate labour time is very large, and then the faithfulness of the original poor, has been less adapted to the needs of the production.
Plus network plate method:
Ceramic appliqué printing is more suitable for direct mesh plate method without the use of two flip photographic plate method, which creates favourable conditions for the appliqué paper plate. Technology is easy to master, better quality, fast plate making, and colour separation out of the negative picture has been the number of dots, you can directly determine whether the original manuscript with the required number of dots, into the number of conformity. Furthermore, after correction of the negative picture dot film, copy the positive picture dot film can be anti-copy. Reverse copy positive picture, dot evolution amplitude than the positive copy of the larger picture level rich, patterned outline is obvious. In addition, you can also use no network highlights mask for layered burst of light, the level can be pulled wide, patterned outline parts of the layout can be deepened, good picture clarity. Finally, the yin map dot film copy yang map dot, yin map dot and photographic film in the copy machine after pumping, so that the yin film and photographic film tightly together, copy the yang picture dots, point type is relatively strong, small dots are not easy to disappear, but ceramic appliqué is generally a special colour dedicated to mastering the characteristics of the direct mesh plate making, how to use its characteristics, the quality of the negative plate to improve is crucial. Repairers must first have a certain degree of basic painting, master a variety of painting characteristics, colour combinations, especially on ceramic pigment properties to have an understanding of the basic skills of learning to draw a good plate and the use of drawing instruments.
Drying process: the printed decal paper for drying process, remove excess water and ink on the paper, so that the pattern more firmly attached to the paper.

3. Decal operation

Apply glue: Apply the appropriate amount of glue in the ceramic blank decal position, the glue should be applied evenly to avoid too much or too little.
Applique positioning: the production of good applique paper accurately placed on the ceramic blank coated with glue, to ensure that the pattern matches the shape and size of the blank.
Adjusting the pattern: Gently press the decal paper with hands or tools to make it fit closely with the ceramic blank, and at the same time adjust the position and angle of the pattern to ensure that the pattern is neat and beautiful.
Remove excess paper: After the glue is initially dry, gently tear off the excess on the decal paper to reveal a clear pattern.

4. Firing treatment

Pre-heating treatment: put the ceramic blanks with good flowers into the kiln for pre-heating treatment, remove the moisture and organic matter in the blanks, ready for firing.
Firing: according to the requirements of ceramic products, set the appropriate firing temperature and time. During the firing process, make sure that the temperature and atmosphere in the kiln are stable, so that the ceramic body and the decal pattern can be fully integrated and cured.
Cooling: After firing, let the ceramic products cool naturally to room temperature. In the cooling process, to avoid sharp temperature changes, so as not to lead to product cracking or deformation.

5. Inspection and packaging

Inspection of quality: the fired ceramic products for quality inspection, check whether the pattern is clear and complete, whether the colour is bright and uniform, as well as whether there are cracks, deformation and other defects in the product.
Packaging and storage: the qualified products will be packaged to ensure that the products are not damaged in the process of transport and storage. At the same time, to do a good job of product labelling and record-keeping for traceability and management.
Through the above steps, you can complete the operation of the ceramic decal process. In practice, it is also necessary to adjust and optimise according to the specific circumstances to ensure product quality and production efficiency.
