Patient information leaflets in Pakistan: printing bilingual inserts
The folded slip inside a medicine box is one of the most demanding pieces of print a pharma brand buys. It carries regulated text in two languages, prints at tiny sizes on paper thin enough to fold many times, and has to arrive folded so precisely that a filling line can insert it into a carton without jamming. Patient information leaflets look humble and are anything but. This guide covers what it takes to print bilingual English and Urdu inserts in Pakistan and get them into the box.
What the leaflet is, and why it is regulated
Most registered medicines in Pakistan ship with a patient information leaflet: composition, indications, dosage, contraindications, side effects, warnings and storage. It is a regulated document, and its content is approved alongside the product. That means the text is fixed, and a change to it follows a controlled revision process, not a casual edit.
Because it is regulated, accuracy outranks everything else on a leaflet. A dropped line, a transposed dose or an out-of-date warning is not a print blemish, it is a compliance failure. The whole production chain, from typesetting to the final proof, is built around getting the words exactly right and keeping them in step with the carton they travel in.
Bilingual English and Urdu typesetting
Many leaflets in Pakistan carry both English and Urdu, and the two scripts do not behave the same on the page. English sets left to right in Latin type; Urdu sets right to left in Nastaliq, with different line heights, letter spacing and justification behaviour. Setting them side by side, or back to back, is a typesetting job that needs someone who reads both scripts checking the proof.
The commonest failures are silent ones: an Urdu line that reflows when a font is not embedded, a diacritic that drops out in conversion, or an English and Urdu column that fall out of alignment after an edit. Insist on a proof that a bilingual reader checks word by word, and keep fonts embedded or text outlined in the final press file so nothing shifts on the way to plate.
Paper and print for very small type
Leaflets are printed on lightweight paper, light enough to fold down small and sit inside the carton without adding bulk. That thin stock, combined with dense body text at small point sizes, is a real printing challenge: ink can spread and fill in fine Urdu strokes, and show-through from the reverse side can muddy legibility if the paper and ink density are not matched to the job.
This is where a printer used to pharma leaflets earns its place. Getting clean, readable type at leaflet sizes on leaflet paper depends on the right ink density, careful register and presses that hold fine detail. It is not a job to hand to a general commercial printer who mostly runs brochures on heavier stock.
Folding to fit the carton
A leaflet is useless to a filling line unless it is folded to an exact, repeatable size and shape. A large printed sheet may be folded five or six times down to a small rectangle that drops into the carton, and every leaflet in the batch has to fold identically. This is precision machine folding, not hand work, and it needs equipment built for it.
PrintVision runs two precision leaflet-folding machines for exactly this stage, folding printed leaflets to consistent dimensions at volume. The folded size is agreed against the carton's internal space up front, because a leaflet a few millimetres too wide when folded will fight the insertion nozzle on the client's line.
Insertion and matching the carton
The folded leaflet is inserted into the carton on the pharmaceutical manufacturer's filling line, usually mechanically. For that to run smoothly, the fold has to be tight and square, the paper weight consistent, and the folded dimensions inside the carton's tolerance. A leaflet that springs open, folds unevenly or varies in size batch to batch is what stops a filling line, and stopped lines are expensive.
So the leaflet specification is really a conversation between three things: the approved text, the carton's internal dimensions, and the filling line's insertion mechanism. Settle all three together, with a folded sample tested against the actual carton, before committing a run.
Keeping leaflet and carton in step
The strongest reason to print carton and leaflet under one roof is synchronisation. When both come from the same supplier, a text revision updates both components together, one quality pass covers them, and one team is answerable if the two ever disagree. Split them across vendors and a wording change can reach the carton and miss the leaflet, or the other way round.
PrintVision has produced bilingual leaflets alongside cartons for pharmaceutical manufacturers since 1989, folding them in-house on precision equipment at the Lahore plant. Whoever prints your inserts, keep the leaflet and its carton on the same desk, in the same approval, and matched to the same batch.
