Color business card common problems and processing methods

First, the color problem:

Because of the small amount of business cards, they are impositional prints, and the colors often have deviations (this is an objective phenomenon, it is difficult to avoid, the deviation is normal within 10%), but because customers/intermediaries do not know about printing, there are often many unnecessary misunderstandings. Therefore, disputes caused by color problems account for more than half of all disputes. For example:

1. The color of printed matter is the same as that of the monitor. This is an unrealistic requirement for customers who do not know about printing and display because printing is printed on the Film/PS version using the four inks of CMYK, and the monitor is displayed in three colors of RGB and different. The monitor causes the same document to be different due to various reasons: the display tubes of different manufacturers are different (that is, the colors of the different monitors are different from each other); the deterioration of the monitor is different. Different; Each person changes the RGB color of the monitor into various values ​​due to different visions and displays different values, so it is unrealistic to require the color of the printed matter to be visible. Of course, the colors displayed by the monitor can be used for reference, and the color of the printed material can be more than 80% of the apparent color.

Processing: If the return of the printed matter and screen is not the same, the company will not generally accept it.

2. The color of the printed matter is the same as that of the ink jet printer. This is an unrealistic requirement for customers who do not understand printing and color printers, because printing is done using four CMYK inks, and printers are printed out with inks. The inks and inks are two different materials, which are produced by different manufacturers. The inks and ink jets that come out of the box cause the colors printed by the same document to differ greatly. However, the printed colors do not meet the printing requirements. Therefore, it is unrealistic to require the colors of the prints to be printed. Of course, ink-jet drafts can also be used for reference. Depending on the goodness of the ink-jet drafts, the color of prints can be more than 70% of the ink-jet drafts.

Disposal: If the product requires a return because of the large difference in color between the printed matter and the ink-jet draft, the company will generally not accept it.

3, require the same color as the original. There are several situations here:
※ The manuscript is not printed by the document provided by the customer to our company. In this case, the color deviation of the manuscript and the manuscript determines the deviation between the manuscript and the printed matter.
※ One of the originals and the printed matter is dumb. In this case, the color of the dumb rubber will be darker.
※ The manuscript is printed out from the documents provided to our company (including the deviation from the last time when the same document was printed again). If the color depth is within 10%, the manuscript is considered normal. Note: Due to printing reasons, the colors with large deviations are: orange color blocks, dark blue color blocks, purple color blocks, brown color blocks, dark green and other darker colors.

Processing: If the color deviation is within 10% of the normal color and requires a return, the company will not accept it. If the deviation is too large, the company will handle it properly.

4. It is absolutely the same that all the prints (including the front and back) must have the same color. Because the amount of cards is small, it belongs to short-run printing. Therefore, it is difficult for the printed matter to guarantee that the colors are absolutely the same, and there will be some small deviations. The deviation is normal at 10%.

Treatment: If the deviation of normal color requires a return, the company will not accept it. If the deviation is too large, the company will handle it properly.

5, on the color of the business card cutting edge of the darker color blocks over the bottom of the problem. This principle is due to the lack of dryness after the printing and the cutting is only the bottom, in fact, due to the pressure on the knife when the cutting is very large, even if it has done a little too much. Of course, after printing for a long time (but there is a delivery time problem) / Design with less dark color (light color is not obvious) / Design try not to put the darker color It's better at the edge of the line (which, of course, will constrain the design), and the best way to prevent it is to use dummy rubber. Guaranteed that there is no end.

6, other color problems. Network gray can not be less than 8%, otherwise it may not be able to present; full version of the bottom gray network, it is recommended to use more than 20% of the gray network, otherwise the network is not obvious; yellow when using the network also use more than 20%, otherwise the color is not obvious.

Recommendation: Customers require stricter color/single size, four-color proofing or color printing is recommended for reference (actually, there are some minor deviations). If the color is too strict, special edition printing can only be used. 1500 yuan.

Second, the cutting problem:

Since color cards are made of coated paper, the cutting is more, and the coated paper is also smooth (the glue is more slippery), and at the same time, the cutting knife will take a position when cutting, so the card may be cut. There will be a displacement of about 1mm (this is a machine factor, it is difficult to avoid), so give attention to the draft, so as to avoid unnecessary disputes.

1. Cut off the logo/text because of inaccurate cutting or make the logo/text too close to the cutting line. This is when the drafting of the logo/text is too close to the cutting line. It is recommended that the logo/letter be tangentially tangent ≥ 3mm when the draft is made.

2. The card wire frame or the color block is asymmetrical (wider in width) due to inaccurate cutting. Under the existing conditions, there is no way to make the cutting absolutely accurate. Therefore, if the requirements are not strict, you can place orders. If the requirements are too strict, it should be stated that our company has the right to refuse to accept this order.

3, because of inaccurate cutting and subsequent processing of the card is not smooth. If a color business card is to be nested for processing (such as color embossing, nesting pressure/silver, etc.), it should be explained to the person in charge of our company. Otherwise, it cannot be returned for processing.

4, because of inaccurate cutting, there are white edges or cut more. The most obvious example of this is a manuscript with a head portrait against a cutting line and without bloodshed. Such a manuscript will make it difficult for the composer to pull it out. If the person's head is pulled out, the face of the person will be cut away, such as the person When the head is pulled back, it will leave a white border. If you do not move it, both are possible. For example, if the head of the complementary head is bleeding, it may not look like it, making the portraits incongruous. This kind of manuscript company has the right to refuse to order.
