The extension of the graphic design file gives an idea about the purpose for which the file can be used; But it does not alone prove that it has been prepared correctly. A PDF may not be suitable for printing, while an SVG may contain pixel-based images. When evaluating the delivery, the content and usage target should be checked along with the extension.
When determining the scope of work with Graphic Designer Selçuk Aker, the editable main file, presentation and broadcast output can be defined separately. More valuable than sending a bunch of extensions to the client is explaining which file will be used where.
Editable working files
AI is the Illustrator working file; It can contain vector drawings, text and placed images. PSD is a Photoshop document; It can be used in layered photo editing and composition works. INDD is the InDesign document; It is one of the file types used in multi-page publication layout.
Editing of these files may depend on application access, version compatibility, fonts, and linked assets. Check for missing image and font warnings before sending the main file. Also consider the terms of use of resources that may be shared.
What job is the PDF being prepared for?
It can be a PDF proposal presentation, digital catalog or printout. Their file size, color, interactivity and production expectations are different. Saying "I sent a PDF" does not mean that the file is in the conditions required by the printing house.
Follow the manufacturer's size, bleed and color requirements for printing. For digital sharing, consider readability and reasonable file size together. Pre-press checklist brings this distinction into practice.
Image formats for web and screen
JPG can be used for photo-based images, PNG can be used for some outputs that require transparency, and WebP can be used for web images. Which one is suitable depends on the support of the broadcast system and the actual resulting quality. Instead of compressing the same photo over and over again, print from the main source.
SVG is used for scalable vector definitions. It can be useful in areas such as logos and icons; The text, filter or embedded image content should be checked. Putting a low-resolution photo in a vector file does not convert the photo to vector.
Separate the delivery package into three folders
- Work: Resources to be edited.
- Publication or print: Ready-to-use and certified printouts.
- Preview and description: Memo showing where the files will be used.
In a sample catalog delivery, separate the digital PDF and the print PDF with clear names. Add project, usage and version information to the file name. For logo-specific submissions, logo file formats guide offers narrower control.
Frequently asked questions
If I save the JPG file as AI, will it be vector?
No. Placing a pixel image into another document does not convert it to a vector drawing.
Are all source files necessarily given to the customer?
The scope of delivery should be determined in the agreement. Editable files, linked resources and their terms of use should be discussed from the beginning.
Can a PDF be used for both web and print?
It can be used in some cases; But the expectations of the two uses are different. It should also be verified that a single file is suitable for both jobs.
