Developing a printing house website using 1C-Bitrix

Print Shop Website Development on 1C-Bitrix

Printing shop operates at production and service intersection: customer expects accurate cost calculation, quality control before print run, and transparent order tracking. Website on 1C-Bitrix covers all three needs — online calculator with non-linear pricing, preflight file check module, and order status system with notifications. Bitrix integrates with 1C:Polygraphia for production cycle sync.

Product Catalog

Printing products in "Catalog" info block with sections: business cards, brochures, leaflets, catalogs, packaging, POS materials, wide-format printing. Each element contains:

• Product Description — with usage examples and finished product photos
• Available Formats — multiple-list property (A3, A4, A5, A6, eurosize, custom)
• Paper Types — binding to "Paper" Highload (coated, offset, design, cardboard — with density)
• Post-Press Processing — multiple list: lamination (matte/gloss), UV varnish, embossing, die-cutting, scoring, folding
• Minimum Run — numeric
• Technical Mackeup Requirements — HTML block with spec: resolution, color space, bleeds

Mackeup Upload with Preflight Check

Customer uploads mackeup via form on detail page. Accepted: PDF, AI, EPS, TIFF. Size limit — 200 MB (via upload_max_filesize, post_max_size, and field settings).

Post-upload, file passes auto preflight check via PHP ImageMagick wrapper (identify, convert):

• Resolution — DPI check (minimum 300 for offset, 150 for wide-format)
• Color Space — CMYK for print; if RGB — client warning
• Document Size — match with selected product format (±3 mm bleeds tolerance)
• Transparency Check — for PDF via pdfinfo (Poppler)

Check result saved to order properties, displayed to client: green — mackeup meets requirements, yellow — warnings (RGB, low res), red — critical (unsupported, corrupted).

PDF preview generated via ImageMagick convert → JPEG, shown to client for visual verification.

Order Tracking

Order goes through production statuses in sale module (bitrix:sale.personal.order.detail component):

• Accepted — order placed, awaiting mackeup check
• Mackeup Checked — preflight passed, queued for production
• In Print — on printing equipment
• Post-Press Processing — lamination, scoring, die-cutting
• Ready for Pickup — on finished goods warehouse
• Shipped — passed to courier or picked by client

Status change triggers OnSaleStatusOrder handler, sending SMS via service (SMS.ru) and email via mail events. Client sees status in personal cabinet — visual progress bar with current stage highlight.

1C:Polygraphia Integration

Exchange via catalog module and custom handler:

• Bitrix to 1C: new orders exported as customer orders with nomenclature binding
• 1C to Bitrix: production statuses update via REST-calls; status change calls CSaleOrder::Update()
• Nomenclature: product reference syncs from 1C with current tariffs

Exchange every 15 minutes for statuses, daily for nomenclature and tariffs.

Deep-Dive: Print Product Calculator with Non-Linear Pricing

Print calculator — most technically complex element. Unlike linear "price × quantity", printing cost depends on multiple non-linear parameters: 100 business cards may cost 5 rubles each, 1000 — already 1.5 per unit. Adding lamination increases cost non-proportionally, stepwise. Paper price depends on density non-linearly.

Data Model

Pricing stored in interconnected Highload blocks:

HlPaper (paper):

HlPrintRun (run tariffs):

HlPostpress (post-press):

Calculation Formula

Total cost comprises:

1. Paper Cost = print sheets × sheet weight × price per kg / 1000. Print sheet quantity from run considering imposition: how many items fit on sheet (depends on item and paper format). Adds technology margin: 3% for runs to 500, 2% for 500–5000, 1.5% above 5000.

2. Print Cost = setup + (print sheets × cost per sheet). Setup — fixed equipment setup, run-independent. Cost per sheet drops stepwise: determined by HlPrintRun row per run range.

3. Post-Press = setup + (units × cost per unit). If run exceeds UF_DISCOUNT_THRESHOLD, apply UF_DISCOUNT_PERCENT discount.

4. Total = paper + print + post-press sum.

Backend Implementation

AJAX handler (/ajax/calc_print.php) receives: product type, format, run, colors, paper type, density, post-press array. Each formula component queries respective Highload via ORM DataManager. Intermediate results cached in $_SESSION for detail display.

Response contains JSON: paper cost, print cost (setup highlighted), each post-press operation cost, total, unit price. Client sees transparent cost structure.

Interface

Calculator embedded in each product detail page. Parameter selection triggers real-time recalc via AJAX with debounce (300ms after last change). Visually on desktop sticky sidebar, on mobile bottom sheet.
