What's the ideal DPI for iPad illustration if I might print it later?

Work at 300 DPI if print is primary use, or create at 150 DPI and upsample with Procreate's scaling for print. Most digital illustration works at 150 DPI fine for screen display. Keep the original high-quality PSD, and if print is needed later, you can always recreate elements at higher resolution or use smart upsampling techniques.

How should I organize layers for a complex character illustration?

Group layers hierarchically: folders for Background, Character, Details, Effects. Within Character, subfold by body parts (Head, Body, Clothing). Use naming like 'head-skin-base', 'head-eyes-shine', 'head-hair-shadow'. This structure speeds editing and makes collaboration easier if someone else needs to adjust.

Should I paint with all layers at full opacity or use blend modes while working?

Paint with layers at full opacity initially to avoid color confusion. Once base colors are solid, add new layers with multiply, screen, or overlay blend modes for shadow and highlight. This non-destructive approach lets you adjust or remove effects without affecting base work.

What's the best format for final delivery to a client?

Deliver PSD (with flattened version), high-resolution PNG (transparent background), and JPEG (solid background). For print, add 300 DPI version in both CMYK and RGB. Include color palette documentation and usage guidelines. Provide lower-res preview for quick client review separate from production files.

iPad Illustration Workflow | Digital Art Production Guide

Overview

Create publication-quality digital illustrations on iPad with organized layer workflows, professional color management, and flexible asset export.

Document Setup

### Canvas Configuration

Create new document at intended output dimensions
For print: 300 DPI, CMYK or RGB per final use
For digital: 72-150 DPI at 1x, 2x, or 4x scale factor
Set canvas size with padding around composition
Enable grid overlay for compositional guidance

### Color Management

Choose RGB for digital/screen (default)
Choose RGB and convert to CMYK later for print (more control)
Set display profile for accurate preview
Create test swatches for spot color matching if needed
Document color space decisions in document notes

### Layer Architecture

Create base layer for white background
Organize layers by major element groups
Use descriptive layer names immediately
Create folder hierarchy: background, characters, details, effects
Keep linework on separate layer from color layers

Painting Techniques

### Linework and Sketching

Create sketch layer at lower opacity for composition planning
Use low-opacity brush for initial rough laying out
Build clean linework on separate layer above sketch
Use monochrome or single-color brush for linework consistency
Lock sketch layer after finalizing composition

### Base Coloring

Create color layers grouped by region or character element
Use flat colors first before adding variation
Apply base colors on layers between sketch and detail
Use clipping masks to paint within established shapes
Create selection from linework layer to constrain color

### Detail and Texture

Add midtones and shadows on separate layers
Use overlay or multiply blend modes for shadows
Use screen or add blend modes for highlights
Build textures with dry brush or texture brushes
Keep detail layers above base color for adjustment

### Effects and Atmosphere

Apply lighting effects on top layer with low opacity
Add atmospheric fog with large soft brushes
Create depth with blur or desaturation of background
Use dodge and burn techniques on dedicated layers
Keep effect layers separate for easy removal or adjustment

Color Refinement

### Hue and Saturation Adjustments

Use Hue/Saturation adjustment layer for color shifts
Adjust individual color ranges (reds, greens, blues separately)
Use Curves adjustment for tonal refinement
Create Levels adjustment for contrast control
Keep all adjustments non-destructive with layers

### Color Harmony

Use Color Dynamics panel to check color relationships
Apply color picker to sample harmonious palettes
Create swatches of dominant colors for reference
Adjust saturation if colors appear muddy
Check grayscale conversion for value consistency

Performance Optimization

### Layer Management

Flatten merged layers when detail phase completes
Delete or merge duplicate or unused layers
Consolidate similar layers to reduce count
Archive high-layer-count versions separately
Limit active layers to 20-30 for smooth performance

### File Size Control

Work at 300 DPI only for final output
Use 150 DPI for most digital illustration workflows
Reduce colors in palette when possible
Flatten background and non-editable elements
Export to lower file size, keeping PSD as backup

Pre-Export Preparation

### Final Composition Check

Zoom to 100% and review entire artwork
Check for stray marks or artifacts
Verify colors are correct and consistent
Confirm no unintended transparency or alpha issues
Review against original concept or brief

### Layer Visibility

Turn off sketch layers before export
Hide reference layers or guides
Show only layers intended for final output
Test different layer combinations for variations
Create separate layer sets for different export versions

### Color Profile

Verify document is in RGB for digital export
Assign sRGB profile for web export
Create CMYK version for print output
Embed color profile in exports if applicable
Document color space in filename or metadata

Export Workflows

### Raster Export Settings

PNG: Transparent background, 8-bit or 16-bit per channel
JPEG: Solid background, quality 85-95%, sRGB profile
TIFF: Uncompressed or LZW, 16-bit for archival
PDF: Preserves vector and raster information

### Multi-Resolution Export

1x (100%): Standard display size
2x (200%): Retina/high-DPI screens
4x (400%): Print preview or large displays
Web optimization: Scale and compress for bandwidth

### Format-Specific Preparation

Web: Scale to appropriate dimensions, convert to sRGB
Print: Ensure 300 DPI at final output size, CMYK or RGB as specified
Social media: Create versions optimized for platform dimensions
Archival: Save as TIF or PSD with all layers intact

Documentation and Delivery

### File Organization

Save PSD with all layers as primary working file
Export flattened versions for specific uses
Create version-dated backups
Organize exports by format and resolution
Document color palette and any special requirements

### Metadata

Add title, artist name in document properties
Include copyright and usage rights information
Document creation date and modifications
Add color space and DPI information to filename
Create README with file format descriptions

### Delivery Package

Include original PSD with full layer history
Provide all exported formats (PNG, JPEG, TIFF, PDF)
Supply color palette as reference
Add brief documentation of layers if complex
Include lower-resolution preview for clients

Best Practices

Name layers descriptively from the start
Use consistent naming conventions across projects
Group related layers into folders
Save frequently during long sessions
Create backups at major completion points
Test exports on multiple devices and screens
Document color space and DPI in every export

Common Pitfalls

Working at too low DPI for eventual print use
Creating too many layers causing performance issues
Forgetting to flatten before exporting
Exporting without verifying background transparency
Not converting to sRGB before web export
Losing original sketch and linework layers
Assuming colors will match across different devices

Troubleshooting

Slow performance: Flatten merged sections, reduce layer count, work at lower resolution
Color banding: Use Noise adjustment layer, increase color depth, check gradients
Pixelated export: Verify export resolution matches intended use, resample at higher DPI
Color shift on export: Check color profile assignment, verify document color mode, test on different screens
