How to thermally transfer a bucket

1. Application of thermal transfer printing for buckets

Due to the rich pattern layers of thermal transfer printing, waterproof and wear-resistant, and the characteristics of one-time transfer molding, thermal transfer printing for buckets has been adopted by more and more bucket manufacturers in recent years.

So, how is the thermal transfer printing of buckets?

2 Thermal transfer printing of buckets
To understand how to thermally transfer a bucket, we must first understand the principle of thermal transfer technology.

The principle of thermal transfer is to perform thermal transfer film printing and thermal transfer processing with different processes according to the material, formation, size, etc. of the substrate.

According to the principle of thermal transfer, thermal transfer printing of buckets requires two steps: thermal transfer film printing of buckets and thermal transfer processing of buckets.

In the entire process of thermal transfer printing of buckets, there are two places that need special attention:

1. Layout of artwork of thermal transfer film for buckets

How to thermally transfer printing of buckets, the layout of artwork is one of the key factors.

As shown in the example picture, most buckets are irregular cylindrical shapes with large mouths and small bottoms, and the printing area is also fan-shaped and curved, so the layout design of the bucket thermal transfer film needs to be carried out according to the layout design principle of the curved thermal transfer film.

a. After unfolding according to the surface shape of the bucket, arrange the bucket thermal transfer pattern according to the unfolded area;

b. The "shrinkage" during the injection molding of the bucket and the "stretching" value of the curved thermal transfer film should be calculated;

c. Check the CMYK value of each color of the bucket thermal transfer pattern through the "PANTON" Pantone color card. However, some special colors such as gold, bank and fluorescent colors cannot be composed of four-color ink overprinting, and must be processed by editing software for spot color layout.

Only after processing by professional layout designers can the real printing area and color block distribution of the bucket thermal transfer be accurately calculated, so as to design accurate thermal transfer patterns, avoid problems such as improper pattern size and inaccurate color distribution due to incomplete calculation, thereby affecting the appearance of the bucket.

2. Selection of heat transfer machine models for buckets

How to heat transfer buckets, choosing the right heat transfer machine model is the primary issue.

The maximum hot stamping diameter of a general heat transfer machine for buckets is between 400-450mm. For buckets exceeding this hot stamping diameter, a special machine needs to be customized according to the actual size of the bucket.

The larger the diameter of the heat transfer of the bucket, the higher the difficulty of hot stamping. Therefore, when customizing the machine model, it is best to choose an experienced heat transfer machine manufacturer to ensure the quality of the heat transfer of the bucket.
