When printing postcards in bulk, maintaining top-tier quality is essential. TPSi’s HP Indigo 15K press delivers offset-quality results even on large print runs. Our Heavy Substrate Option supports 24 pt card stock, providing a sturdy, professional feel. The 7-ink system (CMYK plus three spot colors including white) enables exceptional color range and precise brand reproduction.
Step 1: Choose the Right Paper Stock
For most campaigns, we recommend 14–24 pt cover stock for strength and longevity. TPSi’s Heavy Substrate Option makes thicker 24 pt cards possible without compromising print accuracy or coating quality.
Step 2: Ensure High-Resolution Files
For best results, design files should be 300 DPI and use CMYK color mode. Our HP Indigo press ensures your artwork prints with true color consistency across thousands of cards.
Step 3: Professional Printing Process
TPSi operates an HP Indigo 15K press — combining the flexibility of digital printing with the color fidelity of offset. This press uses liquid ElectroInk for smooth gradients and high-density color coverage on every postcard.
Step 4: Quality Assurance and Proofing
We provide proofing options for all jobs and conduct ongoing quality checks during production. Operators monitor every stage for alignment, registration, and color accuracy — ensuring consistency from the first card to the last.
Step 5: Mailing Integration
All printed materials can seamlessly integrate with TPSi’s mailing services, including NCOA processing, CASS/PAVE-certified verification, and EDDM fulfillment. These are standard services for all mailing campaigns handled in-house, allowing every postcard to meet USPS compliance while maintaining maximum quality and efficiency.
