How to Print on Acrylic with a UV Printer

The following workflow applies to flat acrylic sheets, panels, plaques and similar products.

Exact settings depend on the printer, ink, sheet finish and required product performance.

Step 1: Inspect the Acrylic

Before removing the protective film, inspect the product for:

• รอยขีดข่วน
• Chips
• การแปรปรวน
• การเคลือบพื้นผิว
• Incorrect thickness
• Damaged corners
• กาวตกค้าง
• Protective-film defects

Do not print a damaged blank unless the customer has approved it.

Step 2: Confirm the Printable Side

Some acrylic products have different front and back surfaces.

This is especially common with:

• Frosted acrylic
• Mirrored acrylic
• Coated sheets
• Printed or laminated products
• Laser-ready blanks

Mark the printable side before removing the masking.

Step 3: Remove the Protective Film Carefully

Remove the protective film from the printing side shortly before loading the sheet.

This reduces exposure to:

• ฝุ่น
• รอยขีดข่วน
• ลายนิ้วมือ
• Static contamination

If the product will be reverse printed, keep the protective film on the display side when possible.

Do not leave loose film near the printhead.

Step 4: Clean the Surface Safely

Acrylic should be clean, dry and free from dust.

ใช้:

• A soft damp cloth
• Lukewarm water
• Mild detergent
• An approved acrylic cleaner
• A material-specific anti-static cleaner

Avoid automatically using acetone, lacquer thinner, gasoline or undiluted alcohol. Acrylic manufacturers warn that some aggressive solvents can weaken the surface or cause fine cracks known as crazing. (ACRYLITE®-

If a cleaning chemical is required, confirm compatibility with the exact acrylic sheet.

Step 5: Control Static and Dust

Removing the protective masking can create a static charge.

Static may attract:

• ฝุ่น
• Fibers
• Plastic chips
• ผม
• อนุภาคบรรจุภัณฑ์

These contaminants can become visible beneath white or color ink.

Helpful methods include:

• Ionizing air
• Approved anti-static cleaner
• Damp lint-free cloth
• Clean workbench
• Low-lint clothing
• Covered acrylic storage

Acrylic sheet manufacturers note that removing the masking can generate static and recommend ionized air or suitable anti-static cleaning methods before painting or printing. (ACRYLITE®-

Step 6: Measure the Material Thickness

Measure the acrylic together with any:

• จิ๊ก
• Support board
• Adhesive platform
• Positioning sheet

The combined height must remain within the printer’s supported range.

Do not rely only on the supplier’s nominal thickness.

Step 7: Position and Secure the Acrylic

Place the acrylic flat on the printer platform.

ใช้:

• Vacuum hold-down where available
• A positioning jig
• มุมหยุด
• เครื่องหมายทะเบียน
• Low-profile tape outside the print area
• A flat support board

The sheet should not:

• Move
• Rock
• Bow upward
• Lift at the corners
• Interfere with the printhead

Thin sheets may need full support to remain flat.

Step 8: Set the Printhead Height

An incorrect print gap may cause:

• Blurred images
• หมอกหมึก
• พ่นทับ
• Misaligned white ink
• รายละเอียดลดลง
• ตีหัว

Set the printhead as close as safely permitted by the machine.

Check the highest point of the complete product, not only the center of the sheet.

Step 9: Run a Nozzle Check

ตรวจสอบ:

• สีฟ้า
• สีม่วงแดง
• สีเหลือง
• สีดำ
• สีขาว
• วานิช

Do not print the final acrylic product when the nozzle pattern is incomplete.

White nozzle loss can create:

• Uneven opacity
• Gray areas
• ความไม่สอดคล้องกันของสี
• Visible striping

Varnish nozzle loss can create uneven gloss and texture.

Step 10: Load and Position the Artwork

Import the file into the RIP software.

ยืนยัน:

• Final dimensions
• ปฐมนิเทศ
• Mirror setting
• ชั้นหมึกสีขาว
• ชั้นวานิช
• Printing origin
• Product outline
• Margin
• ลำดับชั้น

When printing multiple acrylic products, use a saved template or jig coordinate system.

Step 11: Select the Print Mode

Choose a print mode according to:

• Artwork detail
• Product value
• ความหนาแน่นสีขาว
• Required speed
• ผลวานิช
• Viewing distance

A high-quality mode may improve:

• ข้อความที่ดี
• การไล่ระดับสี
• White registration
• รูปถ่าย
• โลโก้ขนาดเล็ก

Do not automatically use maximum ink density. Excessive ink can create thick layers, longer curing requirements and reduced surface quality.

Step 12: Print One Test Sample

Before printing a batch, produce one sample.

ตรวจสอบ:

• ตำแหน่ง
• สี
• ความทึบแสงสีขาว
• Layer registration
• Edge sharpness
• วานิช
• การปนเปื้อนพื้นผิว
• การบ่ม

View clear acrylic against several backgrounds, including:

• สีขาว
• สีดำ
• สีเทา
• Natural room light
• Backlight where relevant

Step 13: Perform an Adhesion Test

After the sample has stabilized according to the ink system instructions, test:

• Fingernail resistance
• การยึดเกาะของเทป
• Dry cloth rubbing
• Controlled scratching
• การจัดการขอบ
• Cleaning resistance

If adhesion is weak, investigate:

• การปนเปื้อนพื้นผิว
• Acrylic coating
• ความเข้ากันได้ของหมึก
• การบ่ม
• ไพรเมอร์
• ความหนาแน่นของหมึกมากเกินไป

Do not immediately increase UV power or add more ink without identifying the cause.

Step 14: Use Primer When Required

Some acrylic products accept UV ink without primer, while others benefit from an approved primer.

Primer may improve ink bonding on difficult or coated acrylic surfaces. Official UV printer documentation lists acrylic among the materials whose adhesion may improve with compatible primer. (Roland DG 下载中心-

Apply primer only to the required printing area when possible.

Excess primer may:

• Change surface appearance
• Leave visible borders
• Affect transparency
• Attract dust
• Increase production steps

Test primer and direct printing side by side before choosing the production workflow.

Step 15: Print the Production Batch

Once the test is approved:

• Use the same acrylic supplier.
• Use the same printable side.
• Keep the platform height unchanged.
• Save the RIP preset.
• Use the same cleaning process.
• Check nozzles regularly.
• Inspect every product.

Record the batch settings for future reorders.

Step 16: Finish the Acrylic Product

Finishing may include:

• Laser cutting
• CNC routing
• Drilling
• Edge polishing
• Flame polishing
• การติดตั้ง
• Adding standoffs
• Installing an LED base
• Attaching magnets
• Adding keychain hardware
• บรรจุภัณฑ์

When possible, decide whether cutting should occur before or after printing during the product-design stage.

Printing after cutting may simplify positioning of small finished pieces but usually requires a jig.

Printing before cutting may improve sheet utilization but requires accurate registration between printing and cutting.
