When roll-to-roll sublimation printing is going badly, it's a high-stress situation. Wasted material, missed deadlines, and lost money pile up quickly.
Here is a structured, step-by-step guide on what to do, moving from immediate actions to systematic troubleshooting.
Phase 1: Immediate "Triage" - Stop the Bleeding
```
1. Stop Printing: The first and most important step. Do not continue to run material through the printer if the output is bad. You are just wasting expensive sublimation paper and ink.
```
```
2. Inspect the Last Good Print: Compare the current bad print to the last known good print from the same file. This simple act can often tell you if it's a new problem (like a sudden clog) or one that has been developing over time (like gradual color drift).
```
msgid "3. Run a Nozzle Check Print Head Cleaning Cycle: This is your most valuable diagnostic tool."
msgstr "3. 执行喷嘴检查打印头清洁周期：这是您最宝贵的诊断工具。"
- Run a nozzle check pattern from your printer's maintenance menu.
- ``` Analyze the Pattern:Are there lines missing? Is a specific color (C, M, Y, K, Lc, Lm) completely absent or severely streaky? This will immediately tell you if you have a clogged printhead, which is one of the most common issues. ```
Phase 2: Systematic Troubleshooting - Finding the Root Cause
Problems typically fall into four categories: Printer/Ink, Paper, Design File, or Heat Press.
A. Problemas de impresora e tinta (Los culpables más comunes)
1. Printhead Clogs/Streaking:
- msgid "Symptom: White lines, missing colors, or faint output in the nozzle check." msgstr "症状：喷嘴检查中出现白线、缺失颜色或输出淡化。"
- Solution: Realizar un ciclo de limpieza ligera. Si eso no funciona, realiza una limpieza media o potente. ESPERA 5-10 minutos entre limpiezas potentes para evitar el sobrecalentamiento del cabezal de impresión y dañar los elementos piezoeléctricos. Las limpiezas potentes desperdician mucha tinta, así que úsalas con juicio.
- ``` msgid "Prevention: Print a small nozzle check pattern every day, even if you aren't using the printer. \"Firing\" the nozzles daily prevents ink from drying in them." msgstr "预防：即使您不使用打印机，也要每天打印一个小喷嘴检查图案。每天“激活”喷嘴可以防止墨水在其中干燥。" ```
2. Ink Supply Issues:
- msgid "Symptom: One color is completely absent, even after cleanings." msgstr "症状：一种颜色完全缺失，即使经过清洗后也是如此。"
- Solution: Verifique se os cartuchos de tinta ou o sistema de tinta a granel (CISS) não estão vazios. Certifique-se de que todos os selos herméticos estão intactos em um CISS. Verifique e remova quaisquer dobras nas linhas de tinta. Prime as linhas se o seu sistema permitir.
3. ICC Profile / Color Management Problem:
- msgid "Symptom: Colors are off (e.g., red looks orange, blue looks purple), but the print is sharp and there are no streaks." msgstr "症状：颜色偏差（例如，红色看起来像橙色，蓝色看起来像紫色），但打印清晰且没有条纹。"
- Solution: 确保您在设计软件（RIP软件或Photoshop/Illustrator）中选择适合您特定打印机 + 墨水 + 纸张组合的正确ICC配置文件。使用错误的配置文件打印是获得糟糕颜色的保证方法。如有必要，请重新校准您的系统。
4. Inkqualität niedrig oder Tinte falsch:
- msgid "Symptom: Colors are dull, won't transfer vibrantly, or the ink beads up on the paper." msgstr "症状：颜色暗淡，不会鲜艳地转移，或者墨水在纸上形成水珠。"
- Solution: Siempre utiliza tintas de alta calidad, genuinas o de terceros reputados diseñadas para el modelo específico de tu impresora. Nunca dejes que la tinta se quede durante años; puede degradarse.
B. Sublimation Paper Issues
1. Imprimación del lado incorrecto:
- msgid "Symptom: The ink smudges easily when touched and transfers poorly." msgstr "症状：墨水在触碰时容易晕染，并且转印效果差。"
- Solution: Sublimation paper has a coated side designed to hold the ink. Ensure you are printing on the correct coated side. (A simple trick: lightly moisten your finger and touch each side; the coated side will feel slightly tacky).
2. Low-Quality or Old Paper:
- msgid "Symptom: Ink bleeds on the paper, resulting in blurry prints and loss of detail." msgstr "症状：墨水在纸上渗透，导致打印模糊和细节丢失。"
- Solution: Utilisez du papier frais et de haute qualité provenant d'un fournisseur réputé. Le papier ancien ou endommagé par l'humidité ne donnera pas de bons résultats.
3. Manipulación de papel y humedad:
- msgid "Symptom: Paper jams, curling, or poor ink absorption." msgstr "症状：纸张卡住、卷曲或墨水吸收不良。"
- Solution: Conserve papel en un lugar fresco y seco. El papel de sublimación es muy sensible a la humedad. La alta humedad puede hacer que el papel se enrosque y evitar que la tinta se seque correctamente, lo que lleva a manchas.
C. Diseño y Problemas de Software
1. Low-Resolution File:
- msgid "Symptom: The print is pixelated or blurry." msgstr "症状：打印图像像素化或模糊。"
- Solution: Siempre utiliza archivos fuente de alta resolución (idealmente 300 DPI en el tamaño final de impresión). No puedes arreglar una imagen de baja resolución aumentando el DPI en Photoshop.
2. Incorrect Color Mode:
- msgid "Symptom: Colors are massively off." msgstr "症状：颜色严重偏差。"
- Solution: 确保您的设计文件处于 CMYK 模式，而不是RGB。您的显示器使用RGB，但您的打印机使用CMYK。RIP软件将处理转换，但从CMYK开始可以让您拥有更多控制权。
D. 问题热压（如果转印是问题）
Even a perfect print can be ruined by a bad press.
- ``` msgid "Temperature: Too low, and the ink won't gasify; too high, and it will burn/scorch the fabric or dye. Use an infrared thermometer to verify your platen's actual temperature. Don't trust the dial." msgstr "Temperatura: Demasiado baja, y la tinta no se gasificará; demasiado alta, y quemará/quemará la tela o el tinte. Utilice un termómetro infrarrojo para verificar la temperatura real de su platina. No confíe en el dial." ```
- Time: Pas assez long pour un transfert complet ; trop long et vous risquez de brûler.
- Pressure: Not enough pressure will result in a faint, patchy transfer. Too much can cause "ghosting" or fabric marks.
- Contact: El estampado y la tela deben estar en perfecto contacto. Cualquier arruga o movimiento causará borrosidad.
Phase 3: 长期预防与维护
To avoid future "bad printing" crises:
1. Strikte tägliche Wartung: Machen Sie die Düsenprüfung zu einem Teil Ihrer täglichen Startroutine.
```
msgid "2. Consumables: Stick with a reliable brand of ink and paper. Don't switch without re-calibrating your profiles."
msgstr "2. 消耗品：坚持使用可靠的墨水和纸张品牌。不要在未重新校准您的配置文件的情况下更换。"
```
3. 环境：控制环境。将打印机放置在一个稳定、干净、湿度低的房间内。灰尘是喷头的敌人。
```
msgid "4. Profiling: Invest in a custom ICC profile for your specific printer, ink, and paper combo. It's the single best thing you can do for color accuracy."
msgstr "4. 配置文件：为您的特定打印机、墨水和纸张组合投资一个自定义ICC配置文件。这是您可以为颜色准确性做的最好的事情。"
```
```
5. Keep a Logbook: Note down when problems occur, what you changed, and what the solution was. This is invaluable for diagnosing recurring issues.
```
```
Summary: Comience con la verificación de la boquilla. Inmediatamente le indicará un problema de tinta/cabezal de impresión o un problema de color/software. A partir de ahí, trabaje a través de la lista de verificación de manera metódica. Buena suerte
```
