The corrugated board has a very important impact on printing, directly or indirectly determining the quality of printed matter. Due to different paper properties, different abnormalities will occur in the process of making corrugated cardboard, which will bring various defects to carton printing. Let’s take a look at the impact of different abnormal situations of cardboard on carton printing:
(1)cardboard curved
Cardboard warping is the most common anomaly, which will mainly lead to the following quality problems in carton printing:
1, printing slot running
2, the color is not correct
3, printing shadow
4, Easy paper jam stops in the production process
The recommended solution is as follows:
1, the positive and negative pressure of the cardboard spray steam, flattened with heavy objects
2, emergency practice, folding line, slow down production and strengthen inspection
3. Printing plate adopts auxiliary lamination to avoid shadow and reduce the running value
Here to remind you: must be flat cardboard and curved cardboard separate production.
(2) paper water absorption is poor
In production management, poor water absorption of base paper often leads to the whitening of printing, which is also the most common problem in high-strength cow cards. The carton of high-strength cow card generally has high requirements, which is particularly obvious when printing large color blocks, which is easy to lead to the occurrence of abnormal quality.
Common solutions are as follows:
1, increase the moisture of the paper, using manual wiping, or spray and printing water to select printing
2, ink adjustment, improve ink permeability, and ink quality
3, clear roller to enhance the transfer of ink
4. The hardness of the printing plate is reduced, and the amount of ink transfer is improved
Different solutions can be considered in different situations. Enterprises can make their own solutions according to their own product features, equipment and production environment.
(3)paper material collocation
Due to the increasing pressure of industry competition, enterprises in the material collocation will do incisively and vividly. But products are often unstable, sometimes good and sometimes bad, even the same product is very different. Among them, the most common is that the weight of the septum paper is too low. The most common problems are as follows:
1, the printing is plain, and not in the same position, some good, some bad
2, the pressure is not stable, some qualified and some unqualified
The above two problems are the most difficult to detect. From the perspective of production management, we must check whether there is a problem with the production process of cardboard and carton, and then check whether there is a problem with the printing plate and equipment. Through many tests, in fact, the simplest way is to cut the white part of the cardboard, and then it is found that the septum paper is damaged, leading to no compression, so the same is the case for compression. Therefore, in the configuration of paper separation process must consider the requirements of printing surface and quality, reasonable collocation of materials.

Introduction
Printing plays a crucial role in corrugated cardboard packaging, affecting branding, product presentation, and information clarity. Businesses use printed packaging to enhance marketing appeal, improve logistics, and comply with labeling requirements.
There are two main methods of printing on corrugated cardboard:
Pre-Printing: Printing on linerboard before it is laminated onto the corrugated sheet.
Post-Printing: Printing directly on the finished corrugated board after it has been assembled.
Each method has unique advantages, limitations, and best-use cases, which we’ll explore in this guide.
What is Pre-Printing?
Pre-printing is the process of printing on the linerboard (outer paper layer) before it is combined with the corrugated fluting. This technique is commonly used in high-volume packaging production, where high-quality visuals are required.
How Pre-Printing Works
The linerboard (flat paper) is printed using flexographic, gravure, or offset printing.
The printed sheets are stored in rolls until needed for corrugation.
During the corrugation process, the printed linerboard is laminated onto the fluted medium.
The final sheets are then cut, folded, and assembled into boxes.
Advantages of Pre-Printing
✅ High-Quality, Full-Color Printing
Produces sharp images, vibrant colors, and detailed branding.
Allows for photo-realistic graphics and complex designs.
✅ Smooth and Even Surface
Since printing is done on flat paper before corrugation, there are no distortions, warping, or ink absorption issues.
✅ Cost-Effective for Large Runs
Pre-printing is ideal for bulk production, reducing per-unit costs.
Commonly used in retail and consumer packaging where visual appeal is essential.
✅ Better Coating and Lamination Options
Can apply gloss, matte, UV, or water-resistant coatings before corrugation.
Helps protect packaging against moisture, fading, and damage.
Disadvantages of Pre-Printing
❌ Higher Initial Costs
Requires specialized printing equipment and large paper rolls.
Not suitable for small or customized print runs.
❌ Longer Lead Time
The additional lamination and corrugation process extends production time.
❌ Limited Flexibility for Customization
Pre-printed designs cannot be changed easily for small orders or individual packaging variations.
What is Post-Printing?
Post-printing is the process of printing directly onto the corrugated board after it has been manufactured. This method is widely used for e-commerce packaging, shipping boxes, and bulk storage cartons.
How Post-Printing Works
Corrugated cardboard sheets are fully assembled (linerboard + fluting).
The sheets are fed into a printing press, where ink is applied directly to the surface.
Drying and finishing steps ensure print stability.
The printed sheets are then cut, creased, and folded into final box shapes.
Advantages of Post-Printing
✅ Lower Cost for Small and Medium Runs
No need for large paper rolls or complex setup.
Ideal for short-run and on-demand packaging.
✅ Faster Turnaround Time
Reduces production time by printing directly on finished boxes.
Best for custom orders, last-minute packaging updates, and seasonal promotions.
✅ Flexible Customization Options
Supports variable data printing, including barcodes, QR codes, and personalized branding.
Allows for small-batch printing without extra costs.
✅ Cost-Effective for Shipping and Storage Boxes
Best for functional, industrial, and logistics packaging that does not require premium graphics.
Disadvantages of Post-Printing
❌ Lower Print Quality Compared to Pre-Printing
Printing on corrugated surfaces may cause distortions, color variations, and ink absorption issues.
Not suitable for photo-realistic or complex designs.
❌ Limited Ink and Coating Options
Cannot apply glossy or laminated finishes as effectively as pre-printing.
❌ Ink Smudging and Inconsistencies
Uneven cardboard surfaces can result in blurry or misaligned prints.
