Lesson 3:

Color Management and File Processing

  • Achieving precise and interesting prints comes down to mastering the technical side of color management and file preparation.

    In this lesson, we’ll dive into the details of color management, selecting the right file formats for different printing techniques.

    • Finalize the designs worked on so far by preparing the correct print files, as demonstrated in class.

    • The two exercises completed in class using Photoshop and Illustrator.

Color and File Management

When preparing files for printing on textiles, the choice of file format is crucial to ensure high-quality output and accurate representation of the intended design.

Tips for Preparing Files for Textile Printing:

  • For raster images, ensure a high resolution (at least 300 dpi) to maintain image quality.

    In vector the file can be scaled up and down, if we work with Photoshop or Procreate it is crucial to prepare your design already in size we need to use it, if not bigger, but never smaller.

  • Use CMYK color mode for designs intended for print to ensure accurate color reproduction.

    RGB is suitable for digital displays, while CMYK is preferred for print production in general.

  • If your design extends to the edge of the fabric, include a bleed area to account for potential shifts during printing, cutting and production.

    Consider always a design bleed to allow scaling up sizes for placed prints.

  • Keep your files well-organized, especially if using layered formats.

    Clearly name and organize layers for easy handling during the printing process.

Raster Formats

  • 1. PSD is the native file format for Adobe Photoshop, supporting high-quality, lossless data retention.


    2. Ideal for complex designs, as it preserves layers, transparency, and editable text, making it perfect for projects requiring future adjustments.


    3. Commonly used in design, print, and digital art industries for high-quality artwork where full editing flexibility is essential.


    4. Suitable for textile printing, especially when high detail and precise color management are critical. However, large file sizes may limit compatibility with some non-Adobe applications.

  • 1. TIFF files can use lossless compression, ensuring that image quality is not compromised.

    2. Supports multiple layers, useful for designs with complex layers and elements.

    3. Widely accepted in the printing industry for its high quality.

  • 1. JPEG uses lossy compression, which may result in some loss of image quality, especially at higher compression levels.

    2. Commonly used for web graphics and photographs but may not be the best choice for designs with sharp edges and text.

    3. Suitable for textile printing when image quality is not as critical, or when file size needs to be minimized.

Vector Formats

  • 1. Vector graphics can be resized without loss of quality, making EPS ideal for designs with sharp lines and text.


    2. Supports transparency and layer information.


    3. Often used for logos, illustrations, and other graphics requiring precise lines.

  • 1. Native file format for Illustrator.

    2. Preserves vector information, making it suitable for designs that require scalability.

    3. Supports layers, transparency, and various color modes.

Both Raster and Vector

  • 1. PDF files can contain both raster and vector elements, making them versatile for various design types.

    2. Often used for print production to ensure color accuracy and reliable reproduction.

Color managing for Textile Printing:

  • Most suppliers and printers work in CMYK mode when creating files for print, as this is standard for most printing processes.

    RGB colors might look different when printed, so converting to CMYK early helps ensure color accuracy.

  • If your design requires exact color matching (for brand colors or specific shades), use Pantone color references or HEX codes.

    Pantone provides standardized colors that can be reproduced accurately by printers, making it easier to maintain consistency across various materials.

    On the other hand HEX codes allow for a perfect matching and reproduction of colors in the digital world.

  • Suppliers may have specific color profiles or requirements based on their printing equipment.

    Reach out to confirm these details, as using their preferred profiles helps achieve accurate color reproduction.

  • Different fabrics and textures can affect how colors appear.

    Request fabric samples or swatches with test prints if possible, and adjust colors as needed to keep consistency across all materials in the collection.

  • Include any color profiles or Pantone references in your files so the printer can match colors accurately.

    This ensures that everyone involved in production has a clear reference.

ILLUSTRATOR

2. Blending


• Draw a shape or with image trace obtain an expanded shape

• Duplicate the shape and arrange choosing which one will be foward • Object -> Blend -> Make

• Object -> Blend -> Blend Options -> choose if working with specified steps or specified distance according to your final desiderata

NB: shapes can be moved around before and/or after the blending is active

NB: you can blend more than 2 shapes (see example 2)

PHOTOSHOP

2. Liquify


• Filter -> Liquify

• Play around with different brush size and effects

• When satisfied press Ok

NB: always save an original hidden layer just in case
