Dimensions and Positioning

Besides being able to resize and position your image directly in the Studio, here you can enter specific values. 

• To maintain the image’s proportions, click the lock proportions button:
• Use the   button, to reset the values if necessary.

In this Image module, you can also select the rotation of one or more images that you have selected in the Studio.

Alignments

Available in Caldera Direct-to-Garment RIP.

These options let you align images on the pallet using two modes: Center (no resize) and Center (expand to fit).

By opening “More alignments”, you will also see more alignment options without image resizing that can also be combined: left, center horizontal, right, top, center vertical, and bottom.

Flip

Available in Caldera Direct-to-Garment RIP.

Starting from V1.1.0, two new options have been added to the Image module, allowing you to flip images vertically or horizontally.

Image Adjustments

Adjust luminosity, saturation, hue, opacity, and transparency to enhance image colors in the Studio.

Opacity and Transparency

Available in Caldera Direct-to-Film RIP v2.3 and later.

The "Start Opacity" and "Stop Transparency" sliders rescale per‑image alpha values by defining thresholds: 

• Pixels below "Start Opacity" become fully transparent; 
• Pixels above "Stop Transparency" become fully opaque. 
• Intermediate values are scaled proportionally to correct faulty alpha channels and reduce artifacts (for example, white halos).

Knockout

A knockout refers to the process of removing (or "knocking out") the underlying colors where an object or text will be placed, ensuring that the colors don't overlap.

This prevents the colors from mixing and preserves the true color of the top object or text. It's often used to avoid unwanted color blending when printing layered designs.

The Knockout options appear when one or more images are selected. To use it:

1. Click on the eye dropper icon:   An orange frame will appear in the Studio, indicating “Knockout Preview”.
2. Click on the color of the image(s) that you want to replace with transparency.
3. If needed, use the tolerance slider to broaden the color range to remove.
4. At the bottom, you can also choose to remove the color from all instances of the same color or only from the selected area.
5. Once you are done, don't forget to click Confirm to apply the changes (or Cancel if you are not satisfied).
