Behind seven seals: the secrets of applying images to glass surfaces

Paints, stencils and equipment for silk-screen printing on glass

The technology involves the use of specific paint - polymer compositions are used on glass in silk-screen printing:

• one-component, ceramic and UV - curing occurs under the influence of high temperatures or ultraviolet radiation (with UV paints);
• two-component - UV and chemically curing (with solvents, polymerize at low temperatures) compositions.

Ceramic one-component compositions are the most popular option. They are resistant to mechanical stress, moisture, UV rays and can be applied to outdoor structures.

Ceramic paints are used in large-format printing, as well as for glass work on cars, furniture and household appliances, and shop windows. They are baked into the surface layer using thermal hardening or bending (molding to produce shiny glass). UV pigments are suitable for decorative purposes.

Manufacturers offer innovative combination paints. They consist of two components and are dried under UV rays. They have an optimal balance between mechanical resistance and speed/ease of application - subject to careful surface preparation.

You can even stretch the screen printing mesh onto the frame by hand.

How to paint ceramics correctly?

To paint

For DIY ceramic tiles, it is better to use spray paint for ceramic coatings. Shake the can thoroughly for 20-30 seconds to thoroughly mix the paint. Slowly, with sweeping movements, spray paint over the surface from a distance of 20 - 30 cm.

Sketches of drawings

The first stage of creating stained glass of any type and style is developing a sketch on paper with a pencil. Stencils will help you in this matter.

Transferring an image to a stained glass window in stages:

1. Draw the selected card with squares with a side of no more than 1 cm.
2. Recalculate the number of resulting cells vertically and horizontally.
3. Measure the dimensions of the glass and transfer them to whatman paper or wallpaper.
4. Divide the glass size by the number of previously counted cells.
5. Draw a sheet. You should get the same number of cells, only in a larger format.
6. Transfer the drawing to each cell on the glass, observing the correspondence.

Photo Printing Basics

Both ordinary glass and its many varieties can be used as a basis for photo printing:

• Clarified glass is a transparent base with the most natural color rendering, achieved by reducing the amount of iron in the glass mass;
• Multilayer triplex glass;
• Polished float glass;
• Matted or tinted;
• Plexiglas;
• Lacobel glass with one-sided painting;
• Mirror glass.

When printing, it is necessary to take into account the characteristics of a particular material in order to select the appropriate fixing technology and avoid radical color distortion.

Application of stained glass

Stained glass windows are most often used in interiors for:

windows (children's room, bedroom, kitchen);

interior doors and partitions;

furniture facades;

ceiling decoration.

There are several types of stained glass.

Stacked (classical) stained glass is the most ancient type of stained glass, used to this day in the design of cathedrals and temples.

Creation stages:

1. Sketch.
2. Layout of the pattern on the mounting sheet.
3. Inserting glass parts into the profile.
4. Connecting joints (adhesion).
5. Stained glass painting.

Tiffany stained glass - special opal glass is used, which creates light refraction, making the stained glass window truly mesmerizing.

The procedure for creating Tiffany stained glass:

1. Sketch development.
2. Cutting out parts, polishing.
3. Wrapping of individual parts around the periphery with special copper adhesive foil.
4. Soldering of elements.

Fusing is a special way of transferring an image on a glass surface. The technology consists of soldering individual elements together in a fusing furnace. In this regard, it will not be possible to create such a stained glass window at home.

Filled stained glass – simplified Tiffany stained glass. It is a simple painted stained glass window with a metal broach imitating soldered seams.

Painted stained glass windows are the easiest to create. Even children can make such stained glass. Does not require special equipment or complex manufacturing technology.

The technology of film stained glass is the youngest among those described above. It is a process of tinting glass using special films and then securing it with a lead border. The advantages of the technology include the high strength of finished products.

The essence of imaging technology

The basic principle of silk-screen printing on glass or mirrors is pressing the coloring matter through a mesh matrix and then baking the design. The printing mold is a combination of a template and a grid.

It depends on the type of technological process:

• stencil tension force - the adjustment determines whether there will be a defect in the batch;
• pigment composition - it determines the nature of emulsification and drying of paints;
• type and material of manufacture of screen fabric - for silk-screen printing on glass, matrices made of nylon and similar synthetic compounds are most often used;
• method of transferring images to grids - direct, digital (laser beam), projection, indirect, high-precision, photomechanical.

The basic technology of silk-screen printing on glass includes the following steps:

1. Making a stencil for each color and its preliminary preparation - applying a photosensitive emulsion, drying.
2. Exposure of the template to UV radiation, which hardens the copy layer, development and washing (unexposed fragments are washed out).
3. Drying with a special paste - after it the template is ready for use.
4. Applying a paint layer to glass, drying, heat treatment - the surface is hardened for 2-5 minutes at a temperature from +620 to +660 °C.

The quality of the result is determined by the lineature. This is the number of threads in the mesh per centimeter of length, as well as the thickness and degree of openness. Most often, meshes with a line size of 90-120 threads per centimeter are used. The parameter range is 10-200 threads per centimeter.

The process requires the experience and qualifications of print shop workers

Shutdown

Be sure to rinse and dry your brush before using another color. Lightly wipe the brush with a paper towel. If you see color remaining on it, then rinse your brush again. It is important that the pile is completely dry before you begin painting again.

Examine the painting carefully and see if some areas need to be touched up. It's much easier to do this while the brush is still dry. Also use a toothpick dipped in alcohol to remove excess paint. And the formed bubbles can be pierced with a needle or pin.

Read the instructions on the paint bottle. Some stamps need to dry for several days before they can be used. Others take up to 31 days. Also, some of the paints must be baked in the oven. In any case, the product must be left to dry for at least 48 hours. If it seems sticky when you touch the paint, you need to give it a little more time.

Ancient technologies with a modern interpretation

Silk screens were known to the ancient inhabitants of Mesopotamia and Phenicia, the countries where this technology originated. The Phoenicians invented a way to transfer designs using matrices that hold the paint. It bore little resemblance to modern silk-screen printing on glass, but served as its starting point. Thousands of years later, at the end of the 12th and beginning of the 13th centuries, a technological breakthrough occurred in this area, and the printing method began to look more like the modern one.

The craftsmen of Kamakura, a city on the Japanese island of Nipon, learned to decorate armor with complex relief. They used thread nets onto which they glued decor. The canvas was fixed on a wooden frame. Printers then applied coloring pigments through it using tampons.

Having arrived in Europe during the Middle Ages, silk-screen printing quickly spread among artisans. But it was only in 1907 that the method of working with rubber squeegees, knives that distributed the ink layer over the matrix, was patented, which was most important for the development of technology. They pressed pigment through open areas on the template and greatly simplified the work of printers.

Modern flat screen printing machines apply decor measuring 120x180 cm or more onto a variety of materials.

Second way

It is based on the use of tracing paper. You need to do the following steps:

1. We draw the drawing itself with a helium pen.
2. Disinfect the skin and apply soap.
3. We apply tracing paper and trace the contours with a sharp object.
4. Now let's paint over the drawing.

If you do decide to apply a permanent design to your body, approach this very carefully. The main thing is to choose a good salon, undergo an allergic reaction test and check that all instruments are disinfected.

Application area

Printing technology is used for processing and decorating:

• shop windows and glass, mirror facades;
• glass instruments - when creating markings, measuring scales, dials;
• dishes and bar accessories (glasses, shot glasses);
• glass packaging for cosmetic, chemical and food products;
• furniture - shelves, mirror inserts, stained glass windows, decorative panels;
• souvenir and corporate products - plates, cups, ashtrays and so on.

A separate popular trend is silk-screen decoration of cars. Colored or monochrome images are applied to the inside of the glass. For tuning, special fabrics, stencils, polymer and UV paints are used. The technology is also used in production - for warning labels and edging.

Next stage

Once you've finished outlining your figure, inspect it carefully. If you see lumps or spades beyond the line, carefully remove them with a cotton swab dipped in alcohol. If the paint has already dried, use a craft knife.

Wait until the contour is completely dry. Typically this takes about eight hours. If you need more precise information, check the label instructions as each brand has a different range. If you want to dry the paint faster, use a fan or hair dryer. However, do not set the speed and temperature too high.

Advantages of silk-screen printing on glass

Silk screen printing method:

• provides brightness and clarity of full-color images;
• low-cost - the customer saves money without losing picture quality;
• suitable for large-format printing (up to 4 x 9 meters or more) - grids have no strict size restrictions;
• allows you to apply graphics and designs on cylindrical, relief, flat objects, as well as on rough and mirror surfaces;
• provides increased coverage - the thickness of the application is adjustable, the pattern can be voluminous.

Glass with silk-screen printing looks aesthetically pleasing and blocks some of the ultraviolet radiation from the sun. Decorative imitations are possible - for example, velvet.

Tips for choosing a pattern

When choosing a stained glass design, you should keep in mind a few useful tips:

1. Decide on a plot. It should convey and complement the atmosphere of the room.

1. Lines and colors. Drawings with dark colors visually reduce the space, so if the room in which the stained glass window is located is relatively small, it is better to give preference to light, bright stained glass windows.
2. A stained glass window that conveys a landscape or painting is well suited to a modern interior.
3. Being oversaturated with details can become tiring over time, so you should choose light designs for stained glass with one main element and small additions along the periphery.
