FAQ
Color print job isn’t loading — what should I do?
This usually happens when the CP system is overloaded with multiple jobs, preventing new ones from being processed.
To resolve this:
- Clear some of the existing jobs from the queue to free up space.
- Once space is available, your new job should load and process correctly.
What is the typical expiration date for inkjet inks?
- Inkjet inks generally have a shelf life of about one year from the date of manufacture.
- Flush/cleaning fluids can typically be stored for up to two years.
To ensure optimal performance, always store inks and flush fluids in a cool, dry place and follow the manufacturer’s storage guidelines.
Why I don’t get adhesion on my product?
Adhesion is the ability of the ink to bond effectively to the bottle surface. Poor adhesion can reduce the scratch resistance of the printed design, even if the ink looks fine.
In traditional printing, ink is pressed into the surface, creating mechanical bonding by filling microscopic irregularities.
In UV inkjet printing, ink droplets gently land on the surface without pressure and are cured by UV light. Because there is no mechanical force, adhesion depends on proper surface preparation, surface energy, and the use of primers or treatments.
For optimal scratch resistance, correct surface preparation is essential.
To improve adhesion, try the following:
- Clean the surface – remove dust, oils, or residues using isopropyl alcohol.
- Perform plasma treatment – activates the surface for better bonding.
- Apply primer (PT/CG) – corrects surface inconsistencies.
- Apply Inkjet primer – enhances ink adhesion further.
- Flame treatment – can be used if additional surface activation is necessary.
Following these steps ensures that the ink bonds properly, resulting in sharp, durable prints.
Why is the print quality not sharp?
Blurry or unclear prints can result from several factors. To improve print sharpness, try the following:
- Check RIP software settings – ensure the resolution, print quality, and graphic file format are appropriate for your design.
- Verify bottle positioning – Ensure the bottle is correctly positioned relative to the carriage; the distance between the bottle and print head should be 1.4mm – 1,6 mm.
- Inspect the printhead and nozzles – clogged or partially blocked nozzles can also affect sharpness. Perform a nozzle check and cleaning if necessary.
Following these steps should help restore sharp, clear print quality. If not please contact support@amicatechnology.eu
Why is my printer not connecting to the computer?
Make sure all cables are securely connected. Then, verify the IP settings for both the printer and the computer using the PCS – IP Settings application.
- The printer should be set to IP 192.168.1.20 or 192.168.1.2.
- The computer should be on the same subnet (192.168.1.x).
Correct IP configuration will ensure proper communication between the printer and your computer.
Why my check nozzle is not full?
This usually happens if the printheads have been exposed to UV curing or have dried out. It’s generally not a problem if the printer is being used regularly.
To resolve it:
– Perform a head flush to clear any blocked nozzles
– Run several automatic cleaning cycles.
These steps should restore proper ink flow and full nozzle performance.
Flushing curtain shape must be perfect.
Why isn’t my job appearing in PCS?
If a job isn’t showing in PCS, follow these steps:
- Check the RIP file path – make sure it is correctly configured.
- Verify the Main Hot Folder – PCS will only display jobs from active folders, so ensure the correct folder is selected.
Correcting these settings should make your job appear in PCS for processing.
Why is UV ink still wet after printing?
UV lamp placement – ensure the lamp is correctly aligned and the curtains are fully open to properly expose the bottle.
- Lamp settings in PCS – Verify the lamp settings in PCS (intensity, curing mode) to ensure proper curing.
- Bottle height and UV exposure – adjust the distance between the bottle and lamp if needed (recommended distance: 2 mm) to achieve complete drying.
Why is there a drop of ink on the bottle?
If ink droplets appear on the bottle, check the following:
- Inspect the Negative Pressure (NP) settings to ensure they are correct around 2.0 – 2.2 value
- Check the purple filter in the air system on the the subtank, as it may be clogged.
To test it:
- Remove the purple filter.
Listen to the EM valve: if it clicks after disconnecting the filter from the sub-tank, it is working properly. You can also compare the sound with another working ink line.
If there is no clicking, the filter may be damaged and require replacement.
If the EM valve does not click after the filter is removed, it may be damaged and require replacement.
If that not helping contact us.
Why isn’t calibration responding or completing?
Calibration adjusts the printer for the bottle diameter specified in the job profile. PCS determines the bottle diameter from the job you send it from ColorPrint (RIP).
If the bottle diameter in the template does not match the one currently shown the bottle profile, calibration in the “Calibration” tab will only adjust for the diameter recorded in the Nozzle Check tab (for older systems) or the Bottle Template (for newer systems).
To avoid confusion, it is recommended to perform calibration for specific job. The machine saves calibrations for future use, so once a job is properly calibrated on the bottle, it should not cause problems later.
How to make Bottle/Cup template?
To create a template, enter the main bottle or cup dimensions accurately. Correct values are essential, as they directly affect the calculated printable area.
Follow these steps:
- Create a new Bottle Template and enter the exact dimensions:
- Bottle diameter (or two diameters if the bottle is tapered)
- Bottle length
- Print area length
- Set the Printable Height by entering the maximum printable image height.
For example:- Total bottle height: 230 mm
- Printable body height (excluding the neck): 200 mm
→ Set the printable height to 200 mm
Add the template and enter the main bottle/cup dimensions: Print area height, Diameter of the bottle / set two if the bottle is not equal size.
Bottle Template – Create a template with precise bottle dimensions; set exact diameter, bottle length, and print area length, as incorrect values affect the calculated printable area.
Printable Height – Enter the maximum printable image height, e.g., bottle height 230 mm, printable body (without neck) 200 mm set 200 mm.
Why am I experiencing excessive ink spraying?
Ink mist is the fine spray of ink particles that can escape into the air during the printing process. While most particles land on the target surface, some may remain airborne.
Due to surface tension, a small portion of this mist can settle back onto the bottle, causing unwanted ink droplets or light overspray on the printed product.
- Bottle height setting – ensure the gap between the printhead and the bottle is correctly set between 1.4 to 1.6 mm
- Ink mist catcher fans – verify that they are functioning properly.
Ink mist sponge – inspect and replace the sponge if it is saturated or worn.
Proper alignment and regular maintenance will help prevent excessive ink mist and ensure clean, accurate printing.
