What is the difference between wax-based, wax tree-based and resin-based carbon?

Wax-based ribbons (WAX RIBBON) usually contain a high percentage of wax-based raw materials. These raw materials determine the melting point of the ribbon. The melting point affects the energy level required for printing. Generally speaking, because the melting point of wax is much lower than resin, wax The energy level required for base ribbon printing is much lower than when printing with mixed and resin bases. Because most waxes are softer than resins, the durability of printed graphics is not as good as mixed-based and resin-based ribbons. Most wax-based ribbons have only one layer of coating.

Wax / tree mixed-based ribbons (WAX / RESIN) generally contain a high percentage of resin-based raw materials, which determines the high melting point of this ribbon, and printing with this ribbon is also required to be higher than wax-based ribbon Energy level, because most resins are harder than wax, the scratch resistance and chemical resistance of the printed graphics are also better than wax-based ribbons. Most mixed-based carbon ribbons consist of two or more layers.

The resin-based (RESIN) ribbon contains the highest proportion of resin components, and the energy level required for printing is higher than the wax-based mixed base. Since most resins are harder than wax, the high content of resin makes this ribbon have excellent Anti-scratch and chemical resistance.

Ribbon and paper cooperation

The printing medium refers to the materials that the label printer can print. From the shape of the media, there are mainly ribbons, cards, and labels, and from the material, there are paper, synthetic materials, and fabrics. The main material used to decide which type of ribbon to use is the medium. The following are introduced separately: Paper is divided into high gloss, semi-gloss and matt according to the surface gloss. * High light: Mirror copper plate, glossy paper, etc. * Semi-gloss: coated paper. * Matt paper: offset paper. * Special papers include aluminum foil paper, fluorescent paper, and thermal / thermal transfer paper. Generally, resin-reinforced wax-based carbon ribbons or mixed-based carbon ribbons (IMC W103 and M203) are used for printing high-gloss paper media, especially mirror coated paper, although it is called copperplate, but the surface is a layer of synthetic material. , Should be treated as a synthetic material, using M203 carbon ribbon. The types of ribbons available for semi-gloss paper are resin-reinforced wax-based and general wax-based ribbons (IMC W103E and W103). The matt type can only be printed with W103. Synthetic materials are divided according to materials: * PET (polyester) * PVC (polyvinyl chloride) * BOPP (polypropylene) * PE (polyethylene) * PS (polypropylene) * POLYIMIDE (polymilled vinylamine) * metalized PET There are mainly laser rainbow film, brushed film, gold (gloss, matt) silver (gloss, matt). Compared with paper materials, these materials are stronger and more beautiful, have a wider range of application to the environment, and require higher carbon ribbons. They mainly use mixed-based and resin-based carbon ribbons. The specific type of carbon ribbon depends on the use. According to the requirements and usage environment of the manufacturer, if only anti-friction is required, M203 can be used. If there are other requirements, such as anti-corrosion and high temperature resistance, R303 should be used, but the label can only use PET (180 ℃) And POLYIMIDE (300 ℃) two materials. The above is just the general case, but there are many kinds of materials, and there is a big difference between them. In order to obtain a satisfactory printing effect, multiple tests should be carried out according to their respective conditions to find a suitable ribbon.

Issues to be considered when purchasing thermal transfer ribbons

When buying a carbon ribbon, it is usually necessary to determine the color base of the ribbon (wax-based, mixed or resin-based), and the width and length of the ribbon. In order to choose the right ribbon and get the best printing effect, the following aspects should be considered:

1) What printer is used

In the thermal transfer printing method, the carbon ribbon and label paper are synchronized in the longitudinal direction

In terms of width, the width of the carbon ribbon should be greater than or equal to the width of the label paper,

Less than the maximum print width of the printer. Since the physical size of each printer is different,

The maximum paper roll length that can be loaded and the maximum width that can be printed are also different. In addition,

The working temperature of the print head and the sensitivity characteristics of the carbon ribbon will also have a great influence on the final printing effect.

2) On what surface

Generally speaking, the surface of coated paper is relatively rough, and it should be combined with wax-based or mixed-based

The use of carbon ribbon; while the surface of PET paper is relatively smooth, it should be matched with resin-based carbon ribbon to make

use.

3) Desired graphic durability

If you want the printed label content to have better durability, you should

Choose a resin-based ribbon.

4) Affordable costs

Generally speaking, the cost of wax-based ribbons is the lowest, and the cost of mixed-based ribbons is the second

In short, resin-based ribbons cost the most.

5) Scratch resistance, scratch resistance, smear resistance, corrosion resistance, high temperature resistance and other requirements of the label

If the label is resistant to scratching, smearing, corrosion, and high temperature, it may

Frequently rubbed, the label needs to have strong scratch resistance, then resin should also be selected

Ribbon or mixed base ribbon.

6) At what speed

In the case of high-speed printing, select a ribbon with high sensitivity.

Classification of stickers

Label materials can be roughly divided into the following categories:

Art paper series

Highlight: Mirror copperplate, glossy paper, etc.

Semi-gloss: coated paper.

Matt paper: offset paper.

Synthetic label

PET (Polyester)

PVC (polyvinyl chloride)

BOPP (polypropylene)

PE (polyethylene)

PS (Polypropylene)

POLYIMIDE (Polymilled Vinylamine)

Metalized PET mainly includes laser rainbow film, brushed film, gold (gloss, matt) silver (gloss, matt).

Clothing tag, washed cloth

Special materials (fragile paper, special coated label paper)

Price paper

Composition of stickers

Most labels are self-adhesive labels. The basic components of self-adhesive labels include:

Surface coating-different coating designs for different printer models

Label material-such as paper, pet, pvc, etc., specified according to user needs

Glue layer-there are different gums such as rubber and silicone, and the price varies greatly. Some labels require very good adhesion, and at the same time, they must not damage the surface. You must choose a good gum

Anti-sticking surface layer of backing paper-the role is to prevent the label from sticking

Backing paper-when fixing the label, a good backing paper can make the label easier to save and use
