Capacity depends on the characters, not just the character count. Try square Data Matrix, or Data Matrix Rectangular Extension (DMRE) if your reader supports it. Enlarging the exported image improves print size, not data capacity. For GS1 product, batch and date fields, choose GS1 Data Matrix Rectangular.
