1, determine the size specification.
Disposable paper cups are generally 220 ml or 180 ml, that is to say, the upper opening × lower opening × height is generally 75×53×90 or 70×49×78, and the unit is millimeters. Of course, its specific size should be determined according to the actual design requirements. When calculating, you only need to determine the upper mouth, lower mouth and height.
Step 2 determine the purpose
Disposable paper cups are divided into cold cups and hot cups. The surface of the cold drink paper cup should be sprayed with wax or dipped in wax, because the cold drink will make the surface of the paper cup water, which will make the paper cup soft, so it can be waterproof after being coated with wax. Generally speaking, this kind of wax is very stable and safe at 0 ~ 5℃, but it can't be used for hot drinks, otherwise the wax will melt and the paper cup will absorb water and deform. The surface of the hot drink paper cup will be pasted with a special polyethylene film recognized by the state, which is not only good in heat resistance, but also non-toxic when soaked in high-temperature drinks. We can carry out surface treatment on paper cups according to different design requirements.
3. Determine the printing method
There are three printing methods for paper products: offset printing, silk screen printing and flexography. Offset printing can be used for publicity, but not for drinking water. Although screen printing is good, it is lacking in pattern processing. Flexo printing belongs to green printing, which is less harmful. The made paper cup can be used for drinking water. This kind of printing is a common printing method now, and it has very good publicity effect, simple production and low cost, and is the most commonly used printing method for disposable paper cups.
4. Design mode
Disposable paper cups can be designed without patterns, or related patterns or advertisements can be designed as needed. The pattern designed on the cup body can give people different drinking moods, and it is also a "sign" to promote a certain product. Because the trademark, name, manufacturer and distributor of the product can be designed on the surface of the paper cup. When people drink drinks, they can learn and know the products from this information. Paper cups provide a platform for people to understand these new products.
5. Production
After all the preparations are completed, production can be carried out. In the production process, cutting machines, die cutting machines, printing machines, paper cup forming machines and other machines are usually used. In the process of making hot drink cups, pay attention to adding vinyl film.
What should we pay attention to when designing paper cups?
1. Due to the particularity of the entrance of paper cups, the design should not be too full, and a certain space should be left. Nothing should be designed at the mouth and bottom of the cup to avoid ink pollution when the entrance is stacked. From the aesthetic point of view of design, paper cups with too full patterns will make people feel very chaotic, especially in summer, which is easy to make people feel impetuous and disgusted. Proper publicity, space and angle are the most attractive publicity effects.
2. When designing paper cups, try to avoid purple, dark blue, orange and brown, because these four colors are prone to deviation, which will make the design a mess.
3. The typesetting of paper cup printing must be meticulous, and if necessary, the text can be converted into outline style, which not only looks good, but also plays a certain propaganda role. Because the quality of typesetting will affect the publicity effect of paper cups, this should not be underestimated.
4. Generally, the ink for paper cup printing should contain plasticized free carrier, because this can well prevent the ink film and PE film from shrinking differently due to temperature changes, and it is not easy to curl during paper cup printing.
5, near the bottom of the cup rod, the text design should be raised by 5mm ... Because after the cup is put on the machine, the bottom of the cup must be pressed by 5 mm to ensure the firmness of the bottom of the cup. However, under the high temperature and high pressure of the machine, it is easy to make the graphics and characters near the bottom of the cup bloom, which affects the appearance. Therefore, when designing and making graphics, the text bar pattern near the cup bottom should be raised by about 5mm according to the height of the cup bottom.
