In the printing process of various customized gift boxes, document design and production are the first step. There are various things to pay attention to when making customized gift box documents. If the details are not done properly during the design process, the small loss is wasting time on re adjusting and remaking the sample of the gift box. When the loss is significant, it will result in the entire batch of customized gift box goods being re produced.
Resolution represents the clarity of an image. For printed materials, if the resolution is too small, the finished product is easily blurred, while if the resolution is too high, it will fail to load due to the file being too large. Therefore, the resolution of most materials will be set to 300 resolution.
The resolution requirement for ordinary printed materials is generally 300DP1, in order to ensure that the text and images on the printed materials are clear enough. For example, printed materials such as brochures and flyers typically require a resolution of 300DPI.
For photography, the resolution requirement ranges from 72 to 150 DPI, depending on the size and content of the photo. For example, photo products such as Instagram typically use resolutions within this range.
Spray painting, especially large outdoor posters, requires relatively low resolution, generally between 20 and 72 DP1. This is because the printing size is usually large, and a high resolution can result in files that are too large, which is not conducive to printing and processing.
The P number usually refers to the number of pages. In brochure design and printing, the P-number refers to the total number of pages in the brochure. For example, a 24P brochure actually has 12 pages. When printing a brochure, the P-number is an important factor to consider, as it directly affects the binding method, cost, and final presentation effect of the brochure.
Binding requirements: There are usually two binding methods for picture books, namely saddle stitch and lockstitch binding. Both of these binding methods require the P number to be a multiple of 4. This is because when cutting paper, a double split method is used to ensure effective use of the paper and avoid waste. Therefore, common album P numbers include 8P, 16P, 20P, 24P, etc., all of which are multiples of 4 for easy binding and cutting.
Design specifications: When designing the brochure, design elements such as line thickness and resolution also need to be considered. For example, the line thickness should not be less than 0.076mm, and the resolution should meet the production accuracy of 300dpi-350dpi to ensure printing quality. In addition, the color grayscale should not be lower than 8% to ensure the correct display of colors.
A cutting line is a line or mark on a printed material that indicates the cutting position. Usually used together with corner lines to indicate the position that printing factories should cut when cutting printed materials. The cutting line is usually located at the four edges of the printed material, coinciding with the boundary of the lake gauge. Designers need to ensure that design elements do not extend beyond the cutting line when making printed materials, otherwise it may affect the final printing effect.
CropMarks: CropMarks are lines or markings used to mark the size and cutting position of printed materials. Usually located in the four corners of the brush, the basic final size and cutting position of the brush indicated by the case: the function of the corner line is to ensure that the printed matter can be accurately cut to the predetermined size during cutting, avoiding errors or positioning. In printing design, designers need to pay attention to the setting and position of corner lines to ensure that design elements are not cut off or have excess white edges.
These lines are printed on the corners of printed materials to indicate bleeding areas, which are the parts that will be cut off before binding the printed products. The existence of cutting lines is to ensure the integrity and accuracy of printed materials. They are usually used to reserve cutting positions on the four sides of paper, usually with a 3mm "bleed" reserved.
Die cutting is a cutting process mainly used for post-processing of printed materials and other paper products. By using a die-cutting blade, printed materials or other plate-shaped blanks are rolled into the desired shape or cut under pressure, so that the shape of printed materials is no longer limited to straight edges and right angles.
For printed products with complex edges, a separate die-cutting plate needs to be made to complete this process, which is very common in packaging design. In the die-cutting plate, the parts marked by solid lines need to be cut, and the dotted lines represent folding lines.
Die cutting involves the following elements: raw materials, die-cutting equipment, cutting dies, and cross cutting technicians. The raw materials can be various polymer materials such as paper, belly material, tape, foam, silicone rubber, etc; Die cutting equipment includes various die cutting machines; A knife mold is a mold made according to a predetermined shape; Technicians are responsible for operating equipment and monitoring the production process.
Bleeding refers to the pattern of increasing the outer size of the product, adding some extension of the pattern at the cutting position, specifically for each production process to use within its process tolerance range, in order to avoid exposing white edges or cutting to the content of the finished product after cutting. In order to prevent errors in cutting printed materials, a "bleed" of about 3mm is usually left around the periphery of the manuscript to ensure the integrity of the work.
Bleeding is not always 3mm, different products should be treated separately.
1. The printing of adhesive bound books and brochures must be made white at a distance of 5mm on the back and spine of seals 2 and 3. And perform a 3mm hemorrhage,
2. There should be no bleeding at the midline of the horseback riding nail;
3. The cover and back of the iron ring and rubber strip must have a 3mm void around them;
Printing without bleeding can result in the content being cropped or partially cropped during cutting, causing the content to be cropped. If the text or images around the file are too close to the edge and bleeding is not treated, some content may be cut off during cutting, affecting aesthetics and information integrity.
1. Splitting: Separate the printing part from the post production process, and the document must be labeled with page information to let the printing master know what each page of the document is for.
2. Splicing: Arranging identical or different files onto a fixed size layout and printing them together to reduce material waste.
Splicing printing, also known as composite printing, is the process of combining multiple identical sheets of paper, the same weight, the same number of colors, and the same printing volume into a large plate, fully utilizing the effective printing area of the offset press. Forming the advantages of batch and scale printing, jointly sharing printing costs, and achieving the goal of saving plate making and printing costs. Splicing printing generally accounts for 10-20% more than special edition printing.
The main concern of imposition printing is the ability to form batch and large-scale production. By integrating multiple small batch demands together, the printing cost of a single order can be significantly reduced. In addition, imposition printing can improve production efficiency, reduce waste, and optimize resource utilization.
The above is the summary of ITIS packaging factory over the past 20 years on various matters that need to be paid attention to in the design and production of customized gift box printing documents. These precautions can help customers save more time and reduce waste on costs.
