Now the graphic designers pay too much attention to the effect of the effect and ignore the effect of the landing. Because of the printing process, the paper material is not understood, the effect is far from the object. In fact, printing is a very interesting thing. It is like doing experiments in the laboratory to understand the characteristics of different materials and constantly try to test the material technology that is most consistent with your design.

1. Printed documents

At present, PDF is the most convenient file format for providing customers, printing plants and colleagues. The format of advertising and media files submitted to newspaper and magazine publishers is also based on PDF, and the final output of the printer is also a high resolution PDF file.

Adobe company’s Acrobat, InDesign and Illustrator can save PDF files. In order to avoid changing the settings of files repeatedly and affect the design process, what we need to do before setting up the design is to set up the optimized compression program with the predefined definition. In Indesign, click PDF preset to print quality. Then you can customize the PDF settings, click the file to export, select the.PDF format, and set up the clipping, bleeding, and the registration mark of the printer in a window that pops out. Check the file settings again in Acrobat to ensure accuracy.

If you are writing books in InDesign, remember to choose the “page” option when you export the file, instead of “cross page”, and export each P separately, and the printing shop can help us to block it.

Font embedding is a careless designer must remember things, if the font can not be embedded, usually because it is missing in the folder or the printing factory is limited to it, so after opening, the font will be replaced, if your design is a flower body, and print out into the traditional song, then sad urge. So remember that when you export the files, you need to embed the font, and the prepress check function in InDesign and AI can help us avoid mistakes.

2. Printing paper

The selection of paper is definitely a part of the design process that needs to be taken into account. The thickness, texture and color of paper will affect the feelings of the design image transmission. In the process of doing small samples, several kinds of paper can be selected to ensure the effect.

Paper is calculated in grams (g) or grams per square meter (g/m). The thickness of paper is measured in calipers or millimeters, but the thicker the paper is, the better the quality.

The opacity of paper refers to the extent to which it can pass through the text or image, depending on the density and thickness of the paper. A professional paper company will have its data or experience for your reference.

1). light paper, glossy paper, and wax paper

Different paper surfaces affect the brightness of printing ink. Rough paper will adsorb the ink on the surface and basically do not reflect the gloss. Rough paper is used to print text, such as newspapers and books, for easy reading. However, the ink is printed on the surface paper and will stay on the surface, so more light is on the paper under the font, the light is reflected, the color will be deeper and stronger, and the paper is suitable for book covers, magazines, brochures and outer packing and so on. Wax paper is a paper between rough and glossy. The color of ink on wax paper is not as strong as that of glossy paper, and its surface is not glossy.

2). paint and polishing agent

The role of paints and polishes is to protect the ink and enhance the ink area effect.

Varnish (Varnishes)

A printing coating that can be mixed with other inks and can be used alone. It can be used in glossy paper, glossy paper and wax paper.

The UV curing coating (UV Coating) is commonly known as UV

Smear with liquid and harden with ultraviolet radiation. This coating can be used in rough paper and glossy paper, which can be partially coated or fully covered.

Waterborne rough surfaces (Matte), wax smooth surfaces (Satin) and glossy coatings (Gloss).

The price is relatively high, often as the last layer, so it can only be fully covered.

Laminated material (Lasminates)

It is a plastic interlayer or transparent liquid layer in paper. It has protective effect.

3. Printing color

Printing or printing bias is the most troublesome problem when designers export. The printed products we see are three elements: light, paper and ink. Monochromatic printing is used when budgets are tight or specific colors are used. For example, many brands or companies use specific Pan Tongshai (Pantone) in printing works, which can effectively maintain color unity to ensure the color recognition of the brand. It is suggested to buy a Pantone chromatogram and select relative color number for printing.

Two, three color printing let pant color mixed, two kinds of transparent ink can produce third kinds of color, using two color and three colors to print black and white images can enhance the color effect.

Four color printing is known as CMYK, cyan, magenta, yellow and black. According to the ratio of ink, we can create numerous colors. This is the most common thing we have now.

Pant system: the pant color matching system (PMS) includes a color reference manual and a color matching guide. It can choose the color by selecting the PON color code or entering the exact CMYK value. The printer has these guides and the matching ink, so it is necessary to see the instructions.

Pan Tong color is also known as spot color. There are many kinds of color choices, but we know that the effect of color on different paper will change. For the color closer to the design, for different papers, there are many versions of PMS color, such as matte paper, copper plate, etc.

Calibration detector: first, the designer can understand it, because this is not necessary for us to operate. Correct calibration and use of configuration files can get infinitely close to the colors you see on the screen. Many modern monitors equipped with presets and procedures can help us get basic values. In recent years, the colorimeter used to confirm each color spot is readily available. The colorimeter cycle is used in many different modes to read the current state of the display, and correctly adjust the video card, thereby creating a new ICC configuration text.

Is it very complicated? Yes, the problem of school color is a small goblin. If you have experienced master in the printing factory, he can help you to do everything. If not, you can use a special color. The screen color is not always printed accurately, so when printing the finished product, remember to try several times, do a few more times to ensure that the printing is done in batches.

A lot of people encounter color matching problems are RGB and CMYK, RGB is screen color, CMYK is four color printing, RGB color is not out, can only use CMYK to close the color, so before printing, remember to convert the file into CMYK format, or there will be problems in the printing machine. Other friends are small batch printing, can only go to the digital print shop to print, then the color is inevitable, can only try to close to the effect you want, experienced friends in the proportion of CMYK in mind, but contact with not much printing friends, recommend to print the shop to choose the paper, play small, no words, if you do. Bring good source files, change the value at the scene, it is better to find workers to help them, they are familiar with their machines until satisfactory.

Small Tip:

black

Many designers like to use “Yuan black” or “super black” color matching in a large area. This color scheme is C60 M40 Y40 K100, which is used for image, not text, and is more comfortable than K100 pure black.

Special color

The fan sample guide contains more than 1000 pat color spots, including special versions of gold, pink, noctilucent and so on.

Color matching

There are more than 3000 kinds of pun printing color in the guide book, with the percentage of CMYK tone. The guide was formerly called pat Tong four color simulation spot color guide.

Pant color card

In this guide, the Pantone code ending in C indicates only the color that matches the glossy copperplate. The Pantong code at the end of U is represented as a print color matching the matte surface.

4. Printing process

Several common printing processes are:

The scientific name is called hot press transfer printing, or hot pad printing, commonly known as bronzing and hot silver. It is a method of stamping foil into printing products by means of pressure and temperature, and there is also a cold pad printing.

It can match the effect of convex or concave process, and the color that can be used includes gold, silver, laser, spot color and so on.

1. over UV

It is the above mentioned ultraviolet light, UV is the abbreviation, that is, by UV irradiation to dry curing ink. UV is usually a screen printing process, and now there is offset UV. If the UV is used again on the membrane, the special UV film should be used, otherwise the UV is easy to fall off, bubble and so on.

2. protruding / concave / pressing

The technical name is imprint, and the process of forming local pattern by pressure is the process of pressing the metal plate into two parts: press plate and base plate. It is divided into two kinds: cheap common etching plate and expensive laser relief plate.

Protruding is the use of a convex template (positive template) through the pressure effect, the printing surface is embossed into a stereoscopic embossed pattern (local protruding of the printed matter, so that it has a three-dimensional sense, resulting in visual impact.) It is called “convex”. It can increase the sense of three dimensions. It needs to be made on paper with 200g above.

Press concave is the use of a concave template (negative template) through the pressure effect, the printing surface is embossed into a depression like embossed pattern (partial depression of the printed matter, so that it has a three-dimensional sense, resulting in visual impact.) Also can increase the three-dimensional feeling, paper requirements and convex. Convex and concave can be matched with bronzing, partial UV and other processes.

Embossing is the use of sculptured metal roller to press the surface of the paper to leave a full page texture.

The cover design of Shi Deming’s “why my design is so famous” is combined with bronzing + UV+ bump.

 

3. die cutting

The die cutting process is based on the requirements of the design of the printed material to make special die cutting tools, and then, under the action of pressure, the printing or other materials are rolled and cut into the forming process of the required shape or cut.

It is suitable for products with more than 150g of paper as raw material, and try to avoid approaching patterns and lines of palpable lines.

4. golden onion

It is to put a layer of glue on the paper before pouring the gold powder on the glue.

 

5. YO

Just like spring, objects are mostly plastic. They are usually used on the spine of calendars and notebooks.

6. film mulching

The paper is pressed to a transparent plastic film, with crystal film, light film and matte film. Many places call differently, and are not environmentally friendly.

7. flocking

It is to brush the glue on the paper, then attach a layer of material similar to fluff, so that the paper feels and feels a bit of flannelette.

8. brush edge

On the edge of the paper, brush more than one layer of color, suitable for higher thickness paper, often used in business cards.

9. screen printing

It can be operated on flat objects, spherical objects, curved surfaces, and even concave and convex surfaces, such as clothes, wood and so on, which can be printed with great flexibility. The ink layer after printing is thick and strong. Screen printing process equipment is simple, easy to operate, printing and plate making is simple, low cost and strong adaptability.

Little colored eggs

When it comes to screen printing, here is a wonderful pigment that can be combined with silk screen printing, called a reversible temperature changing color paint, called Thermochromatic ink. It features a particular color at room temperature, and the color vanishes to colorless after heating, and it is immediately restored to its original color after cold. The process is reversible.

Another is the laser engraving (Laser Cut), which is the use of laser technology to write the text on the object, the technology engraved with no marks, the surface of the object is still smooth, and the handwriting will not wear. Engraving machine has three kinds of carving patterns, hollowing out, carving, and three kinds of strokes.

The use of laser engraving and cutting is very simple, like using computers and printers to print on paper. AI files that are directly vectored can be “printed” to the engraving machine easily. The processing precision can reach 0.02mm.

The above basic requirements for the daily printing, if you want to be particularly severe, please buy a book, “print”, there are hundreds of printing technology to provide choice, but not every printing plant can be achieved.
