A Brief Discussion on Print Schemes for Digital Printers

Photo printers are widely used in advertising production, quick printing of graphics and text, etc. For beginners, understanding their printing methods is helpful for a better start and choosing the right equipment. Here are the common and special printing methods of photo printers, as well as beginner-friendly tips: 
I. Common Printing Methods
Depending on the type of ink and the application scenario, the common printing methods for photo printers can be mainly classified into the following categories: 
1.

Water-based ink solution (indoor photo printing) 

Features: Fine picture quality, no odor, low ink cost. 

Applicable scenarios: Indoor posters, display stands, self-adhesive materials, slides, photo paper, KT boards, etc. 

Limitations: Not waterproof or sunproof. If used outdoors, it must be covered with a film. 
2.

Weak solvent ink solution (for outdoor photo printing) 

Features: Waterproof, sun-resistant, scratch-resistant. Can be sprayed directly outdoors for 1-3 years without the need for film application. 

Applicable scenarios: Vehicle wraps, single-ply films, outdoor light cloths, glass wraps, barriers, etc. for long-term outdoor advertising. 

Limitations: There is a slight odor, and the cost of ink and the machine is slightly higher. 
3.

Dual-purpose solution (indoor + outdoor) 

Features: By changing the ink system or configuring two sets of pipelines, one machine can handle both water-based ink and low-solvent ink. It is currently the mainstream choice for advertising stores and can cover 90% of regular advertising sheets. (Not recommended) 
4.

Six-color ink scheme 

Features: Based on the CMYK four-color system, the addition of light cyan (LC) and light red (LM) enhances the natural color transition, making it suitable for depicting skin tones and soft colors, and improving the printing quality. 

II. Special Printing Solutions
With the advancement of technology, photo printers (especially UV printers) can now achieve a greater variety of high-value-added special printing effects: 
1.

Color and white color printing scheme 

Through the three-layer printing process of "color ink - white ink - color ink", the color saturation is higher, the color reproduction is better, and it can be displayed on both sides. It has significant advantages in window displays and light box advertisements. 
2.

Laser coating printing solution 

A transparent varnish is added on top of the printed surface, making the surface appear shiny, beautiful and with a smooth texture, thereby enhancing the visual effect of the picture. 
3.

Planar 3D Printing Solution 

Compared with ordinary flat color printing, the patterns have a stronger three-dimensional effect, with clear textures and a more realistic appearance. 
4.

Thermal升华 printing solution 

Using thermal energy to transfer the pigments onto the medium, the colors blend to form continuous color gradations. This method is particularly suitable for scenarios such as portrait photography where high skin texture requirements are needed, and it can be preserved for a long time without fading. 
5.

Water-based soft packaging / flocking solution 

For customized printing solutions for special materials (such as BOPP, PE, PET for soft packaging or flocking fabrics), they feature environmental friendliness, no odor, and bright colors. 
III. Is it suitable for beginners to start with?
Absolutely. For beginners or newly established advertising agencies, a photo printer is an excellent entry-level device. The reasons are as follows: 
1.

Low operational threshold: The operation of current photo printers is not complicated. Novices only need to master basic computer layout, connect the machine, and select the printing schemes for corresponding materials (such as photo paper, vehicle stickers, etc.) before they can start printing. 
2.

The equipment selection is diverse and offers good value for money: 

Entry-level models: There are many entry-level devices available on the market that are suitable for small advertising stores or startups (such as the Aldrich 1.6-meter single-head model). The prices usually range from 15,000 to 20,000 yuan, and they can be recovered quickly, making them ideal for beginners to "just buy without thinking". 

Main recommendation: If your budget is sufficient, it is recommended to directly choose the Aldrich 1.8-meter dual-head model (equipped with the I3200 nozzle). This is the current mainstream configuration in the market, featuring high stability, low failure rate, and numerous after-sales service outlets, making it suitable for long-term development. 
3.

Enhanced intelligence level: Some new photo printers have incorporated the "multi-solution intelligent printing function". When changing different materials, the machine can automatically adjust the height of the carriage and the feathering mode, eliminating the need for cumbersome manual adjustments. This enables beginners to easily produce high-precision images. 
Tips for beginners to avoid common pitfalls: 

Resolutely avoid the older generation of sprinkler heads (such as the fifth generation, 5113, 4720 or hot-blowing type sprinkler heads), as these types of sprinkler heads have short lifespans, are prone to clogging, and have high maintenance costs. 

Don't buy low-priced unbranded machines just for the sake of saving money. The subsequent maintenance and downtime costs will be much higher than the price difference of the machine.
