Perfect Printing Starts with Precision Proofing: SiHai's Artwork Proofing Process

At SiHai, we understand that for a custom aerosol tin can, a flawless final product begins with an uncompromising attention to detail. The art of printing tinplate requires precision, and artwork proofing is the critical step that ensures your design is reproduced perfectly on every single can. We believe that superior quality is born from rigorous pre-production communication. That's why we collaborate closely with you to ensure every detail is perfect before your project moves into full-scale manufacturing.

Our comprehensive proofing process is designed to safeguard your brand's vision and ensure the highest quality in tinplate printing. It consists of three core steps of verification.

Step 1: Digital Artwork Proofing
Upon receiving your digital artwork file, our Quality Assurance Lab conducts an initial review. We meticulously analyze the design for the unique considerations of printing tinplate, checking for potential issues in content, color reproduction, and positioning on the aerosol tin can template. We resolve any needed adjustments with you upfront. The final digital proof is then sent for your approval, a process that typically takes just 2-3 business days.

Step 2: Color Range Board Approval for Tinplate
Following digital approval, we create physical Color Range Boards specific to the printing tinplate process. These boards are essential for defining the approved color tolerance limits—the Light Limit and Dark Limit—for your aerosol tin can. All mass production will be strictly matched to this standard, ensuring vibrant, consistent color that stays within the agreed-upon limits across every production batch.

Step 3: Pre-Production Sample (PPS) – The Final Check
Before mass production begins, we create a Pre-Production Sample (PPS) using the actual manufacturing line. This provides a true-to-life representation of your final aerosol tin can, allowing for a final confirmation that the printing tinplate result meets your exact expectations. For urgent orders, and only with your permission, we may proceed based on approved color boards, with the PPS sent alongside the first batch for your confirmation.
