1. limited budget _Things to Check Before Buying a Used UV Printer

If you need a UV printer but your budget is tight, you might decide to purchase one through Alibaba in China.

Or, you might decide to buy a used UV printer from Korea.

In this situation, you have no choice but to search for equipment based on price on secondhand sites or forums.

If the exterior looks neat, you might visit the store, see how it prints, and after some discussion, decide to purchase.

 

 

2. 알면 알 수록  _Things to Check Before Buying a Used UV Printer

At first, I thought everything would be fine as long as it printed, but after a few iterations and actual print orders were produced,

“The colors are weird?”

“After printing, I see some kind of line!”

“Why is the image so grainy?”

“Why is the ink peeling off this material?”

“After printing, it feels kind of sticky.”

The more I work with the UV printer, the more I notice various issues.

 

3. If any problem occurs _Things to Check Before Buying a Used UV Printer  

While you can get answers to some minor issues from the place you purchased your used equipment, if you encounter any issues, it can be incredibly frustrating.

Without answers from the place you purchased it, you’re left searching the internet for solutions to similar problems.

Thus, your top priority becomes solving the problem, and you find yourself struggling to find solutions one by one.

If it’s resolved, that’s great, but if it’s not, you start to seriously consider, “Should I just throw the equipment away?”

 

II. Things to Check Before Buying a Used UV Printer  

1. Check original purchase location _Things to Check Before Buying a Used UV Printer

 

No matter how pristine the equipment is, if it’s imported directly from China, rather than purchased through a Korean dealer, the risks are significant.

• If a problem arises, there’s no one to turn to but the place of purchase,
• and since the person purchasing the equipment isn’t an engineer, you can’t expect a solution.
• Even if you’re able to secure a contact point in China through the place of purchase, it’s difficult to expect smooth after-sales service in China because the equipment wasn’t purchased directly.
• Even if you purchase ink from a Chinese distributor, sales volume is low, making it difficult to expect proactive after-sales service.
• The biggest problem is that if the Chinese distributor discontinues a model, it can be difficult to obtain the board if a problem arises.
• If you’re purchasing used equipment directly, always verify that it was purchased through a Korean dealer.

 

It’s also best to avoid purchasing equipment that’s too old.

• The head you’re using may be discontinued, driving up prices and ultimately eliminating supply.
• The electronic board may also no longer be available.

 

2. Print quality _Things to Check Before Buying a Used UV Printer

It’s highly recommended that you check the print head condition and print quality with the seller using a test image.

A. First, you should look at the nozzle test photo and then examine the entire print as it was printed.

B. Are there any visible lines on a solid color or white background?

 

C. To what extent are small prints displayed?

See below for what small print means in terms of print quality.

Rather than checking for good print quality, you should check that the images printed on used equipment are of sufficient print quality for the work you need to do.

3. Rip software _Things to Check Before Buying a Used UV Printer

 

Once you’ve achieved the desired print quality, the next step is to determine the printable file and color.

• You must check whether the printable file is only Photoshop or AI files.
• Some people, unfamiliar with the concept of ICC profiles, blindly adjust the colors in the Photoshop file to achieve the desired color.
• It’s also a good idea to check whether the RIP software has applied the ICC profile and whether it has a color graph adjustment function.
• Once you place an actual print order, customers will likely request color changes.
• If changing the original file colors is difficult, you’ll have no choice but to adjust the color graph in RIP software to achieve the desired color.
• While you can change colors using Photoshop or AI files, it’s not easy if you don’t have the printer’s default color values.

 

4. Consumables and spare parts _Things to Check Before Buying a Used UV Printer

There are three scenarios:

Equipment sold in Korea with a certain number of units sold.

• Electronic boards, spare parts, and consumables can be obtained through that seller.
• In some cases, after-sales service may be available for a fee.

Equipment sold in Korea is limited in the number of units sold for that model.

• You should inquire whether the electronic board for that equipment is still available.
• Sometimes, the model may be discontinued and the electronic board for that model may no longer be available.

If you are importing used equipment purchased through Alibaba,

• It’s recommended to take a photo of the equipment’s nameplate and contact the Chinese seller to inquire about the availability of the electronic board.
• You should also check the availability of spare parts.

5. “Can I buy ink from Alibaba?” _Things to Check Before Buying a Used UV Printer

Purchasing ink through Alibaba means

• it ignores the ICC profile currently assigned to the ink, which can result in incorrect colors.
• Matching incorrect colors with standard colors is not easy.

Even if you’re willing to sacrifice color accuracy, if you want to change ink, you should purchase ink that specifically identifies the head.

Ink not specifically designated for the head can cause various problems.

• Even if ink loads and pumps, it may not jet at all.
• Even if it jets, ink may fly off during printing and scatter around the printer.
• If the flyoff is severe, the nozzle may clog during printing, creating streaks.

 

Do you have after-sales service? You should also check whether parts, including the board, are available.
