In industries such as intelligent manufacturing, warehousing and logistics, building materials processing, and electronic hardware,Flexible, clear and stableProduct identification is no longer an additional item, but a need for compliance, traceability, and anti-counterfeiting.
Zhejiang Kerisi Technology Co., Ltd. focuses on the research and development and manufacturing of handheld marking equipment. Today, we will give you a detailed explanation of the two trump cards.--**handheld inkjet printer**with**Handheld laser marking machine**Application scenarios and core advantages help you choose the right logo solution in one stop.
1. Hand-held inkjet printer: Easy to accompany, spray immediately
KoleshiA full range of handheld inkjet printers, with **TIJThermal foaming technology**As the core, it has a lightweight body and one-click operation to meet the needs of rapid coding in multiple scenarios.

core advantages
**Ultra-light and can be held with one hand**
Ultra-light, compact body with lanyard/Ergonomic handle makes it easy to work in warehouses, construction sites and outdoors.
**Compatible with multiple materials and rich colors**
Adapt to plates, cartons, pipes, cables, metals, plastics, etc.; support black/red/Huang/blue/green/white/Invisible and other multi-color inks, water-based/oily/Quick drying options.

**High-definition printing, all-purpose content**
300–600DPIHigh precision, spray printing height**2–100mm**(Multi-sprinkler model), supports text, pictures, bar codes, QR codes, serial numbers,25languages+Handwritten input.
**Maintenance-free, easy to operate**
The ink cartridge can be replaced in a snap-in manner, eliminating the need to clean the nozzle;2.4–7inch touch screen, use it immediately after booting,UDisk quickly import font/Pattern.

**Scenarios Unlimited**
There is no need to fix the production line. Large, special-shaped, and packaged products are directly sprayed, and the positions are not picked for multi-angle printing.
###applicable scenarios
-food/Daily chemical: production date, shelf life, batch number
-building materials/Pipe: specification, model, meter,LOGO
-logistics/Storage: outer box barcode, destination, batch
-electronic/Hardware: serial number, material code, traceability code
-Small batch customization: graphics, QR code, promotional information

##2. Handheld laser marking machine: permanent marking, once and for all
forPermanent, highly wear-resistant, and strong anti-counterfeitingFor marking requirements, Karez handheld laser marking machine is etched in non-contact, and the mark will never fall off, be scratch resistant and corrosion-resistant.
###core advantages
**Permanent identification, anti-counterfeiting and anti-smuggling**
Laser etching goes deep into the surface of the material, and friction, sun exposure, and chemical corrosion are not blurred, achieving full life cycle traceability.

**Lightweight and integrated, mobile work**
Light nose**1.1kg**,7inch HD touch screen+Detachable large-capacity battery, outdoor/Stable battery life can also be achieved in scenarios without power supply.
**High-precision, non-destructive machining**
Red light positioning has high repeatability; non-contact type does not damage the workpiece, and adapts to complex structures of flat, curved, and concave and convex surfaces.

**Zero consumables save money in the long term**
No ink required/Solvent consumes only energy and has a long laser life**10million hours**, maintenance costs are extremely low.
**Take all materials**
Metal (stainless steel/aluminum/Copper), hard plastics, wood, leather, ceramics, etc. can be marked with high quality.

###applicable scenarios
-automobile/Machinery: Part number,VINCode,LOGO
-electronic/Hardware: serial number, QR code, model parameters
-Medical device: unique identification code, sterilization batch
-wenchuang/Gifts: Personalized carving,LOGO, pattern
-Large equipment: marking in situ on site, no need to move workpieces
