印大相、油畫相製作 FAQ

Professional Photo Printing/ Fine Art Printing - FAQ

We are specialist who can turn your digital file into high-end art piece, but common file-related problems can affect the overall result. We hope this FAQ helps you avoid them and get the most out of our service.

1 What should I pay attention to, when choosing a file?
2 How to know if a file has sufficient resolution?
3 What is aspect-ratio?
4 What is bleeding-area?
5 Is the color of the print accurate?


1 What should I pay attention to, when choosing a file?
- Image resolution has to be sufficient.
- Print & file aspect-ratio must be the same.
- Whether the subject/ logo/ signature is placed too close to the image-border (which falls into the bleeding area)
- Enlarge the image to “100% crop” to check for defects, such as blurring, excessive noise, sensor-dust or undesired facial expressions.


2 How to know if a file has sufficient resolution?
- Unit of resolution is dpi(ppi) – dot(pixel) per inch.
- E.g., if the length of your file is 4500px, and if you want to print it at 30”, 4500/30=150dpi print-resolution.
- In most cases, we'll rate 200dpi as very good, 150dpi as good, 120dpi as decent, and 72dpi as an acceptable bottom-line.
- As a wall decoration, the proportion of the photo and the wall is of higher priority because it affects the overall presentation/aesthetics more, as long as resolution is still decent at more than 120dpi.
- A high-res image can be blurry because of digital zoom/ enlargement, camera-shake, subject out-of-focus, or poor lens performance etc.,


3 What is aspect-ratio?
- It is length:height proportion of the image.
- E.g., if long-side / 3 x 2 = short-side, it is 3:2; if long-side / 4 x 3 = short-side, it is 4:3
- It is 3:2 for 135-format, APS-C cameras; 4:3 for 120-format, 4/3 and most smartphone cameras.
- Print & file aspect-ratio must be the same, otherwise part of the image will disappear in the printout (red area shown below)
What is Image Aspect-Ratio
- If there's aspect-ratio mis-match we will suggest the correct print size


4 What is bleeding-area?
- In most types of printing including some common photo printing, a few mm of the file-border can't be printed on the paper, this disappeared area is called "bleeding-area". Every truely professional designers & photographers know this limitation and avoid placing important subjects too close to the border.
- Our giclee-printing can print everything without this bleeding, but when a print is framed, image-border will still be lost/not viewable because it is covered by the frame rabbet or passe-partout (or trimmed away for some frameless-style products), we call it "frame-bleeding".
- Therefore, the viewable-size of a framed image is usually smaller than the original print-size.
- Avoid placing important subject/ logo/ signature too close to the border (lower-left) otherwise part of them may disappear because of frame-bleeding (orange border of the lower right).
Bleeding Area Meaning


5 Is the color of the print accurate?
- Giclee-printing is well-known for its wide color gamut and high color accuracy, when the print-operator is an expert, and high-quality print-media is used, which is our case.
- Oversimplified speaking, most monitors aren't accurate, so that a color-accurate print-out may look different from an inaccurate monitor. Monitor accuracy can be achieved by calibrating with a spectrophotometer in a professional way, do not rely on its automatic functions.
- If we judge that the brightness of your image isn’t good enough, we will provide suggestions/ solutions.
- Color-management is very complicated knowledge, overlooking just one rule/ law or without actual working experiences can cause serious misconception. Please trust that we are the PROFESSIONAL when we raise a problem and propose a solution.
