Stamp printing is used to print detailed drawings or images on different items, irregular objects with a cylindrical or flat surface. The method used to print on pens, desktops, lighters, keychains, scrapers, toys or other objects made of plastic, metal, glass, leather, wood, paper or others is the same: the ink is transferred from the cliché to the article using a silicone pad.
The diversity of applications makes this technique the most practical, the least expensive and the most versatile.
Pad printing is the fastest and most accurate technology, allowing the printing of logos with a large number of colors (polychrome) on most surfaces.
Because the polychromies involve obtaining colors from the CMYK base color optical mixture (see the example opposite), it is suggested not to use them in small texts or fine lines. The risk is to get drawings with a fuzzy outline. For these cases, it is suggested to use a full color of the Pantone or HKS color chart.
Some items require pre-treatment or post-treatment. For good adhesion of the ink, the metal articles must be dried in furnaces. The drying time can be up to 4 days.
This technique is used to print images or graphic templates on different items such as t-shirts, jackets, hats, etc. and on the most diverse materials such as paper, plastics, textiles or metals. What makes the difference each time, according to the specific basis, is not the process but the ink. The first rule of the screen is that the base material should be flat.
The method is simple and consists in applying a layer of ink on the base material through a mesh. Printing can be done in one or more colors manually, automatically or semi-automatically. The polychromatic image can only be made on white materials and involves the realization of color combinations by optical mixing of CMYK basic colors.
For darker materials, the image is separated into more specific colors (up to 10 colors) with a basic white layer. These brighter colors give clarity to the image.
This technique involves the digital printing of the desired image on a special sheet, cropping it after a predefined shape and then applied to the article by hot pressing.
Is most suitable for small quantities up to 50 pieces, sometimes be used for the prototype. If you think of the name and numbers on the back of a football t-shirt, they are machine-cut from vinyl and applied by a heat transfer press. The design or text is permanently applied to the garment and is very durable. On most fabrics, it can be washed up to 60 degrees and more. There is usually no Set-Up fee for this technique.
The impression can be made on a transparent sheet, white or colored. The advantage of the transparent sheet is that it allows to see the color of the custom item and allows for complex designs, but it can be applied only on white or light colored items.
Sublimation is the method of applying a special filmed image to a final surface (ceramics, metals that have a polyester layer, synthetic textiles) using three basic ingredients: ink, heat and pressure. Sublimation ink is unique in its ability to pass from solid to gas without going through a liquid form (such as dry ice). The conversion is initiated by heat and controlled by pressure and time.
Sublimation is the process by which color passes from the printed sheet to the final surface (t-shirts, cups, puzzles, etc.). Sublimation only works on white surfaces. Sublimation works better on synthetic materials or other pretreated materials to accept sublimation inks.
Sublimated images have great resistance to washing, scraping or other rubbing processes because the image is protected inside the material. The difference between sublimation and other transfer techniques that use dye-based or dye-based inks is that sublimation guarantees 100% strength for applied images while other techniques do not.
TRANSFER IN SERIGRAPHY
With this technique, the image is printed using a screen printing process on a base material, in particular paper. Then, using the pressure and the high temperatures, it is transferred to the article.
As with a classic silk screen, images can be applied on paper, plastics, textiles and metals.
The difference between the screen transfer and the silk screen is that with the screen transfer can be realized images brighter, sharper, with small texts and clear details. This difference can be seen on the side images.
Although screen-printed transfers use the same inks and processes as other types of screen printing, the use of transfers has several advantages:
• The biggest advantage of this technique is that it allows quality control of the impression and its correction before being applied to the article.
• Print on demand
• Fills and last-minute orders are easy
• Win time and money
• Offer better customer service
DIGITAL TEXTILE PRINTING
The advantages of digital printing:
Digital printing makes it possible to print your project on clothing directly from the computer data, which has the effect of eliminating the technical costs found on all other marking techniques. This technique also brings the flexibility of production of the unitary piece to the large series while maintaining an image definition and a touch almost non-existent.
Digital printing refers to methods of printing from a digital image directly to various media. It generally refers to professional printing where small print jobs of desktop publishing and other digital sources are printed using laser printers or large volume inkjet and / or large volume inkjet printers.
In many processes, the ink or toner does not penetrate the substrate, like the conventional ink, but forms a thin layer on the surface that can be adhered to the substrate using a heat-treated melt (toner) or UV process (ink).
This technique highlights the logo with elegance, the logo being embroidered on the surface of the object. Embroidery can be done on smooth surfaces (clothing) or uneven surfaces such as hats, backpacks, bags, etc.
Depending on the item and the size of the image *, there are several sizes of embroidery maximum (see the image of side).
• The minimum letter size is 5 mm high;
• The thickness of the line must be at least 1 mm thick;
• Gradients are not possible
This technique uses a laser beam to print a text, logo or drawing by engraving on the surface of the object. Usually used for metals, this technique can also be used for plastic and wood.
The result of the engraving is influenced by the engraved material. The metal can be engraved in several ways:
• One of them is the engraving directly on the surface of the object and according to the type of metal, its aspect is modified.
• On painted or anodized metals, the paint layer will be removed and the color of the metal will be revealed (gold or silver).
This technique is similar to laser engraving only which uses a laser beam made with a glass tube with CO2. It is specially dedicated to non-metallic materials and is successfully applied to wood, plastic, leather and organic materials (fruit).
The result of the engraving is directly influenced by the engraved material. For example, the wood becomes dark brown.
This mechanical engraving technique uses a small diamond to print a text or logo on the surface of objects. This technique is mainly used to engrave glass objects, but also metals or marble. Opposite to acrylic or other plastics, shards of glass look like marble and granite. This leads to creating small scratches on the glass that reflects the light, or iridescent color appear as if blasting.
Glass engraving can be performed on: glasses, bottles, ashtrays, trophies, etc.
Metal / plastic engraving can be used to create medals, signs and other objects.
Doming is a printing technique where several materials, mainly stickers, are applied with a transparent coating. A resin layer (epoxy resin) gives a 3D lens effect, as well as additional depth and brightness to the colors.
The coating can be applied in liquid form in many different ways. Once applied, the polyurethane liquid flows to the edge of the label and stops (due to the surface tension of the liquid), hardening into a transparent dome.
The first layer is the material of the label. The second layer is the ink. The label can have multiple colors (CMYK), photo-quality graphics, or plain text. The ink is applied using a screen or digital printing technology. Once the ink has cured (dried), the labels are laser cut or cut and the waste between the labels is removed from the press sheet. The liquid polyurethane material is then applied to the labels on the press sheet and allowed to cure.
This is a dry printing method in which a heated mold is used to apply graphics to a surface. The logo will keep the color of the material. This technique allows dry printing on materials such as leather, leather replacements or paper, using a preheated high temperature press.
Logos printed with this technique have a defined appearance, keep the color of the material and have great resistance over time. Hot stamping gives printed articles an elegant appearance and is particularly used for notebooks, folders or other leather goods.
