Mengoperasikan Mesin Cetak Digital - Teknik Grafika

Summary

This instructional video provides a step-by-step guide for operating a digital printing machine, tailored for students in the Graphic Production program. It covers the preparation of design files, machine setup, material loading, software configuration, and the printing process. Key tasks like performing nozzle checks, adjusting print settings for optimal quality, and cleaning the print head are emphasized. The video concludes with post-printing steps and machine shutdown procedures, aiming to ensure that students gain hands-on experience in using the machine effectively and safely for high-quality printing.

Takeaways

• 😀 Ensure that the design is created and exported in the correct file format (TTF) before printing.
• 😀 Always turn on the computer first, followed by the digital printing machine, for proper initialization.
• 😀 Use the 'Print Manager' application on the computer to control the print process and machine settings.
• 😀 Perform an ink head check by pressing the 'Positive Present' button to load ink into the print head.
• 😀 Clean the print head regularly with a tissue in a single direction to maintain quality prints.
• 😀 Place and properly feed Flexi material onto the machine, ensuring it is aligned and secure.
• 😀 Adjust the 'Feeding' settings to correctly move the material through the machine, and use weights to prevent slack.
• 😀 Use the ripping software to configure media size and print settings, such as the number of color passes for sharper results.
• 😀 Perform a nozzle check to ensure the print head is functioning properly before printing.
• 😀 Start printing by selecting the file in the digital printing application and adjusting the settings (color, alignment, etc.).
• 😀 Once printing is completed, use the cutter to trim the printed material and adjust the heat and fan settings for drying.
• 😀 Properly shut down the machine by manually moving the print head, pressing the emergency stop button, and cleaning the machine afterward.

Q & A

What is the purpose of this video tutorial?

The video tutorial aims to teach students and teachers how to operate a digital printing machine, especially for those in the Graphics Production department at SMK Muhammadiyah 2 Muntilan.

What is the first step before operating the digital printing machine?

The first step is to prepare the design using graphic design software and export it in a compatible format (TTF) for printing.

How should the machine and computer be turned on?

The computer should be turned on before the machine. Afterward, the Print Manager application should be opened, and the machine's status should be set to 'Ready'.

Why is it important to check the print head before starting the printing process?

Checking the print head is important to ensure the ink flows correctly. A nozzle check ensures that all colors are printing evenly, preventing poor print quality.

What should you do if the print head is not functioning correctly after the nozzle check?

If the nozzle check shows uneven printing, you should manually clean the print head and refill the ink to ensure smooth operation.

How should the flex material be prepared for printing?

The flex material should be placed on the roll at the back of the machine. It is then fed forward and adjusted using the feeding buttons to ensure it is properly aligned.

What is the purpose of the 'Ripping' software in this process?

The 'Ripping' software is used to process the design files for printing. It converts the design into a printable file, adjusts media settings, and configures the quality (such as the number of passes).

What does adjusting the 'passes' setting in the Ripping software do?

Adjusting the 'passes' setting controls the number of times the print head will pass over the material. More passes result in better print quality with sharper and more vibrant colors.

How is the material fed into the machine after it is prepared?

The material is fed into the machine by using the feeding buttons, ensuring it is correctly positioned and aligned. The material is then rolled through the machine as per the printing requirements.

What should be done after the printing is finished to ensure the machine is properly shut down?

After printing, the print head should be moved to the right side of the machine using the software. The machine should be turned off using the 'Emergency Stop' button, and the print head should be cleaned and secured.

Why is it necessary to clean the print head after use?

Cleaning the print head prevents ink from clogging the nozzles, ensuring consistent print quality for future prints. It also helps maintain the longevity of the machine.
